Boosting immune system to fight Covid-19: Is it possible?

Immune boosting is a trending topic these days with the COVID-19 pandemic. The concept of “immune boosting” is scientifically misleading and often used to market unproven products and therapies. There is no current evidence that any product or practice will contribute to enhanced “immune boosting” protection against COVID-19. This lack of evidence has not stopped wellness gurus with vested interests, and commercial entities from propagating notions of boosting immunity. Internet and popular press are flooded with messages of this nature resulting in an abundance of misinformation circulating online. The public is increasingly going online for health information and questions persist around the kinds of inaccurate information the public is absorbing and the impacts it may be having on health-related decisions and actions.

 

What are Immunity Boosters?

Immunity boosters are products which claim to be able to support your immune system so you aren’t as likely to get sick. Additionally, if you do get sick, taking the supplements will make your illness pass faster. There is no scientific and clinical evidence in humans to support claims of ‘immunity boosting’ foods and other products which supposedly enhance immunity. The body has its own immune system which fights against viral and bacterial invaders. With a normal immune system, we are capable of protecting ourselves against most infections but with certain situations the infection manages to overcome our immune system and cause serious disease and even death. The current Covid 19 pandemic is such a situation. We are in the grip of a spike in infection with over 1000 cases per day seen during the last few days. Total deaths from the pandemic in our country is nearing 700 and the total cases up to now amounts to around 111,800.

With no scientifically established cure for Covid-19 yet and the available recommended treatments limited to severe cases and being not so effective, recovery in most cases has largely been reliant on the human body’s natural defence, the immune system. Fighting the infection by boosting our immune systems had been the buzzword since the beginning of the pandemic. This has led to many misconceptions, misinforming and misleading the public. Improving the diet, taking vitamins and herbal products, lifestyle changes are proposed as ways of doing this. As a result, the market has been flooded with an array of products that claim to boost one’s immunity.

One of the common misconceptions is that high doses vitamin supplements and other minerals and nutrients boost one’s immunity. Ayurvedic concoctions, fruit juices, vitamin pills, zinc tablets have flooded the market with an array of products that claim to boost one’s immunity. Promoters of these products indicate that the body’s natural defences can be strengthened or enhanced by the consumption of certain foods, herbal products or the use of specific products.

Is there robust scientific evidence to support these claims for immune system boosting? The answer is no. Immunology experts believe that there is no way for healthy adults to improve their immunity through foods or other products. The immune system is very complex and these claims about boosting immunity are irrational and unscientific.

 

The Immune System

The immune system is activated by things that enter the body that the body doesn’t recognise as its own such as bacteria, viruses or even particles that cause allergy, like food, drugs and pollen. Most pathogens have a surface protein on them that the immune system recognizes as foreign. These are called antigens. Then the immune system sets in motion a complex process that fights the invader – this is the immune response.

There are two kinds of immune responses in the human body. The innate immune response is the first to kick in and is common among all animals. It is non-specific and immune cells mount an immediate attack on antigens. The response is subsequently replaced by the adaptive immune response, which tailors defences based on the kind of pathogen that is being encountered. The innate immune response consists of white blood cells like neutrophils, macrophages, and monocytes, while the adaptive response involves Lymphocytes -T cells and B cells, as well as antibodies produced by these cells as a specific response to the invader’s antigens. Stimulated immune systems release chemical proteins known as pro-inflammatory cytokines in large numbers, which can cause soreness and pain. So boosting immunity may lead to unwanted inflammations causing swelling, redness and pain locally and fever and other organ damage.

The Internet searchers will find that the myth of “boosting immunity” is extremely pervasive. Of the approaches that claimed to boost immunity, the top ones were diet, fruit, vitamins, antioxidants, probiotics, minerals. Interestingly, vaccines, the only proven method that enhances our immune response to an infection is ranked very low. One of the biggest misconceptions is that consuming more vitamins than required helps the immune system. It has been proven, time and again, that mega-doses of Vitamin C or of any kind of vitamin are not effective on the body at all. Another misconception is that zinc tablets can play a role in mitigating Covid-19. However, this isn’t backed by evidence either.

Zinc is not an immunity booster. It is an essential mineral for the body which is a ‘cofactor’ for a large number of proteins and enzymes. A cofactor is a non-protein chemical compound or metallic ion that is required for an enzyme’s activity as a catalyst. Like zinc, vitamin C is also a cofactor, and is important for the body to function. So, if you have a deficiency of these essential micronutrients, you will face a problem. But, if a person does not have any such deficiency, an excess amount of these taken does not improve one’s chances of fighting off a virus. Vitamin C and Zinc deficiencies are very rare unless someone is starving or following an extreme diet depleted of nutrients. Iron and Iodine deficiencies are seen in communities and more than immune deficiency they cause other problems.

An extremely active immune system, can also be problematic. In severe Covid-19 cases, the body launches an aggressive immune response resulting in the release of a large amount of pro-inflammatory proteins. This is known as a cytokine storm and is one of the common causes of death in Covid-19 patients. A cytokine storm occurs when the body’s immune system goes into an overdrive, killing healthy cells and causing organ failures. Several research studies suggest that the cytokine storm causes lung injury and multi-organ failure. So, if this is the case boosting the immune system in a Covid patient is not a wise thing to do.

 

Market interests add to the myth

The truth is natural immunity in normal people cannot be improved. There are immunocompromised individuals with a poor immunity who are susceptible to infections due to certain illnesses, and how can they stay safe from this highly infectious virus that spreads rapidly? The most effective way is by keeping our communities safe.

 We can do this by attending to the public hygiene of the population exposed to the infection. Providing safe drinking water, providing clean air, providing adequate nutrition — are ways of keeping the people healthy and strong to fight any infections. There are parts of our country fortunately not as bad in India, without access to these basic health requirements. Achieving social distancing in these communities that live in overcrowded households is impossible.

This background, and a new infection with no treatment, led to various interested parties with good and bad intentions in promoting the myth of immune boosting. They have become self-proclaimed experts exploiting this crisis, putting forth all kinds of miraculous non allopathic substitutions. As allopathic medications to be approved, a rigorous procedure has to be observed, they resorted to the easier approach of promoting quick remedies in traditional and herbal products. Unproven ‘natural’ remedies came to the fore in our country in this background where people felt helpless. The vaccine, the only proven way of boosting the immunity of an individual and the population against a specific disease was not available around this time.

There are added dangers in such situations. There may be a lot of drug-drug interactions. If people are consuming allopathic medicines, and then also start consuming these medicinal herbs, the components of the herb will interact with the drug resulting in unknown complications. These unapproved medications can have toxic effects on your kidney, liver and other organs.

Even during the Spanish Flu pandemic in 1918 companies jumped in on the opportunity to hail themselves as immunity boosting drug producers. However, no products were ever proven to be effective in improving immune responses.

Maintaining a normal immune system

A poor immune system is seen in people with certain ailments. Some are born with defects in their immune system and they are known as immunodeficiencies. People with chronic illnesses like diabetes and auto immune disorders are also vulnerable to catch illnesses easily as their immune systems are weak. People on immunosuppressant medications like steroids and cancer drugs also have a weakened immune system and easily catch infections and develop serious complications easily.

Lifestyle is key for keeping your immune system normal and ready to act with an adequate response when necessary. For now, there are no scientifically proven direct links between lifestyle, exercise and enhanced immune function. Researchers are exploring the effects of diet, exercise and stress on the immune response. There are indeed processes that do affect our immune cells and improve their responses. The best one of them, perhaps, is exercise. Many studies have shown that moderate exercise of less than 60 minutes can improve the circulation of anti-inflammatory cytokines, neutrophils, natural killer cells, T cells and B cells. This can work effectively — not for combating diseases at a specific point in time, but to combat stress hormones in general, which can suppress immune cell function. Extremely high intensity exercise leads to a short duration of compromised immunity, increasing risk for disease in this time period. This is one of the reasons marathon runners or professional sports persons tend to catch a fever or cold in the days following a sporting event. Regular exercise is known to improve cardiovascular health, lowers blood pressure, helps control body weight. Therefore, adopting general healthy-living strategies make sense since they are likely to have other proven health benefits. But whether they help to boost the immune system is a controversial issue with no proven answers.

The immune system can also be compromised by many lifestyle habits such as smoking, which is known to affect T and B cells, among a host of other parameters. Diseases like diabetes by themselves result in compromised immune systems. This is why diabetic patients are particularly susceptible to infections. Obesity is another condition with a weak immune system as it predisposes to the development of other illnesses like diabetes and hypertension. There appears to be a connection between poor nutrition and immunity and this is a problem especially in the elderly. Poor nutrition can lead to micronutrient malnutrition, in which a person becomes deficient in some essential vitamins and trace minerals. Deficiency of these can result in a poor immune response to infections. Older people tend to eat less and often have less variety in their food. In them dietary supplements may have some beneficial effects and they should discuss this with their doctors. Taking mega doses of vitamins do not help and can even be harmful.

Every part of your body, including your immune system that fights against infections function better when protected from unwanted damage and bolstered by healthy-living styles. These are – not smoking, taking a diet high in fruit and fibre, exercising regularly, maintaining a healthy weight, avoiding alcohol or consuming in moderation, getting adequate sleep, washing hands regularly, developing good food habits, minimizing stress.

However, there currently exists no evidence of any consumable foods or products being able to induce an improvement in immune function. Although some preparations have been found to alter some components of the immune system, so far there is no evidence that they actually boost your immunity to the point where you are protected against infection. The only scientifically proven way to boost immunity, the immune system, and an immune response is through vaccinations. Vaccines prime your immune system to fight off infections before they take hold in your body.

So, where do we stand today? Vaccines to boost our immunity against Covid, prevention of spread and catching infection by proper wearing of masks, washing hands and maintaining social distance. These are the scientifically proven methods and others appear to be market-driven myths.

Your six-year-old needs a tablet like a fish needs a smartphone

THE GREAT DIGITAL RETHINK — PART II

Nordic countries handed tablets to toddlers and called it early childhood education. Now they’re taking the tablets back, handing out pencils, and hoping nobody noticed. Meanwhile, the Global South is still signing the tablet contracts. Someone should probably warn them.

The Tablet Arrives in Preschool

It is 2013, a government minister stands in a preschool in Stockholm, handing a shiny tablet to a four-year-old. Press cameras click. A press release announces that Sweden is building the digital classrooms of the future. The child, who until recently had been learning to hold a crayon, now swipes confidently at a screen. Innovation! Progress! The future!

Fast forward to 2023, the same Swedish government, or at least its successors, announces that preschools were wrong to make digital devices mandatory. Children’s reading comprehension is declining. Books are going back on the shelves. Pencils are making a comeback. The preschool tablets are being quietly wheeled into storage, and nobody wants to talk about the press release.

What Finland Actually Did — And Is Now Undoing

Finland has long held a special place in the global education imagination. When PISA scores are published and Finland sits at or near the top, education ministers from Seoul to São Paulo take note and wonder what they are doing wrong. Finland is the benchmark. Finland is the proof that good education is possible.

Which makes it all the more significant that Finland, in 2025, passed legislation banning mobile phones from classrooms. Not just recommending restraint. Not just issuing guidelines. Banning them, with teachers empowered to confiscate devices that disrupt learning. The law covers both primary and secondary schools. It came after years of evidence that children were distracted, and that Finland’s own PISA scores had been falling.

But the phone ban is only part of the story. The deeper shift in Finnish primary education has been a quiet reassertion of analogue fundamentals. Early literacy is being treated again as a craft that requires time, patience, practice and, crucially, a pencil.

Sweden gave tablets to toddlers. Then took them back. The pencils were in a drawer the whole time.

Sweden’s Spectacular U-Turn

Sweden’s reversal is arguably the most dramatic in recent educational history, because Sweden had gone further than most in embracing early-years digitalisation. The country had not merely allowed devices in preschool, it had in places mandated them, treating digital interaction as a developmental right alongside physical play and social learning. There was a logic to it, however misplaced: if the future is digital, surely children should encounter that future as early as possible.

The problem is that young children are not miniature adults navigating a digital workplace. They are human beings in the early stages of acquiring language, developing fine-motor-skills, building concentration and learning to regulate their own attention. These are not processes that are enhanced by a swipeable screen. Research on early childhood development is consistent on this point: young children learn language through conversation, storytelling, and physical manipulation of objects. They learn to write by writing, by the slow, muscular, tactile process of forming letters with a hand.

By 2023, Swedish education authorities had seen enough. Reading comprehension scores were down. Handwriting was deteriorating. Teachers were reporting that children were arriving in primary school unable to hold a pen properly. The policy reversed. Books came back. Cursive writing was reintroduced. The national curriculum was amended. And Sweden became, instead, a cautionary tale about what happens when you swap crayons for touchscreens before children have learned what crayons are for.

Australia: Banning Phones at Lunch

Australia’s approach to primary school digitalisation has been somewhat less ideologically charged than Scandinavia’s, and accordingly its reversal has been more pragmatic than philosophical. Australian states and territories arrived at phone bans largely through the accumulating pressure of parent complaints, teacher frustration and growing evidence that smartphones were damaging the social fabric of school life, not just in classrooms, but in playgrounds.

Queensland’s ‘away for the day’ policy, introduced in Term 1 of 2024, was notable precisely because it extended beyond lesson time to cover break times as well. This was a direct acknowledgement that the problem was not simply digital distraction during learning, it was the way that always-on connectivity was transforming childhood itself. Children who spend every break time on a phone are not playing, not resolving social conflicts face to face, not developing the unstructured social skills that primary school has always, if accidentally, taught.

The cyberbullying dimension added particular urgency in Australia, where research showed that many incidents of online harassment between primary-school children were occurring during school hours, facilitated by the phones sitting in their pockets. Banning the phone at the school gate did not solve the problem of online cruelty, but it did remove the school day as a venue for it.

The Science of the Pencil

The cognitive argument for handwriting in primary education is, it turns out, and far more interesting than the popular ‘screens bad, pencils good’ slogan suggests. The research on note-taking in university students, the finding that handwritten notes produce better conceptual understanding than typed notes, has a more fundamental parallel in primary education.

When a young child learns to write by hand, they are not merely practising a motor skill. They are encoding letters through physical movement, which activates memory systems that visual recognition alone does not reach. Studies in developmental psychology suggest that children who learn to write letters by hand recognise them faster and more accurately than those who learn through typing or tracing on screens. The hand, it appears, teaches the brain in ways the finger-swipe does not.

This does not mean that digital tools have no place in primary education, nobody sensible is arguing that children should graduate from primary school unable to use a keyboard. The question is sequencing and proportion. The emerging consensus, hard-won through a decade of failed experiments, is that foundational literacy and numeracy need to be established through analogue means before digital tools are introduced as supplements. Screens can follow pencils. Pencils, it turns out, cannot follow screens without catching up on what was missed.

The hand teaches the brain in ways the finger-swipe does not. And it took a decade of falling scores to rediscover this.

The Rest of the World Is Still Buying Tablets

Here is the uncomfortable part. While Finland legislates, Sweden reverses course and Australia bans phones from playgrounds, a large portion of the world’s primary schools are doing the opposite. Governments across South and Southeast Asia, Sub-Saharan Africa and Latin America are actively expanding device programmes in primary schools. Tablets are being distributed. Interactive whiteboards are being installed. AI tutoring apps are being piloted. The logic is identical to the logic Finland and Sweden followed 15 years ago: modernise, digitalise, equip children for the future.

The vendors selling these systems are not telling ministers about the Swedish U-turn. The development banks financing device programmes are not adjusting their models to reflect the OECD’s inverted-U curve. The international consultants advising education ministries are largely still working from a playbook written in 2010.

The lesson of the Nordic reversal is not that screens are evil, it is that screens at the wrong stage, in the wrong proportion, without the right pedagogical framework, undermine the very foundations they are supposed to build on. That lesson is available. The question is whether anyone is listening.

What Primary Schools Actually Need

Literacy and numeracy are not enhanced by early device saturation. They are built through reading aloud, through writing by hand, through mathematical reasoning with physical objects, and through the irreplaceable medium of a skilled teacher who knows their students.

Technology in primary education works best when it supplements a strong foundation, not when it substitutes for one that has not yet been built. Sweden and Finland did not fail because they used technology. They failed because they used it too extensively, and without asking what it was actually for. That question — what is this for? — is the one that every primary school system in the world should be asking before it signs another tablet contract.

Government is willing to address the past

Published

Minister Ratnayake

Minister Bimal Rathnayake has urged all Sri Lankan refugees in India to return to Sri Lanka, stating that provision has been made for their reintegration. He called on India to grant citizenship to those who wished to stay on in India, but added that the government would welcome them back with both hands if they chose Sri Lanka. He gave due credit to the Organisation for Eelam Refugees Rehabilitation (OfERR), an NGO led by S. C. Chandrahasan, the son of S. J. V. Chelvanayakam, widely regarded as the foremost advocate of a federal solution and a historic leader of the Federal Party. OfERR has for decades assisted refugees, particularly Sri Lankan Tamils in India, with documentation, advocacy and voluntary repatriation support. Given the slow pace of resettlement of Ditwah cyclone victims, the government will need to make adequate preparations for an influx of Indian returnees for which it will need all possible assistance. The minister’s acknowledgement indicates that the government appreciates the work of NGOs when they directly assist people.

The issue of Sri Lankan refugees in India is a legacy of the three-decade long war that induced mass migration of Tamil people to foreign countries. According to widely cited estimates, the Sri Lankan Tamil diaspora today exceeds one million and is often placed between 1 and 1.5 million globally, with large communities in Canada, the United Kingdom and Australia. India, particularly Tamil Nadu, continues to host a significant refugee population. Current figures indicate that approximately 58,000 to 60,000 Sri Lankan Tamil refugees live in camps in India, with a further 30,000 to 35,000 living outside camps, bringing the total to around 90,000. These numbers have declined over time but remain one of the most visible human legacies of the conflict.

The fact that the government has chosen to make this announcement at this time indicates that it is not attempting to gloss over the human rights issues of the past that continue into the present. Those who suffered victimisation during the war may be encouraged that their concerns remain on the national agenda and have not been forgotten. Apart from those who continue to be refugees in India, there are more than 14,000 complaints of missing persons still under investigation according to the Office on Missing Persons, which has received tens of thousands of complaints since its establishment. There are also unresolved issues of land taken over by the military as high security zones, though some land has been released, and prisoners held in long term detention under the Prevention of Terrorism Act, which the government has pledged to repeal and replace.

Sequenced Response

In addressing the issue of Sri Lankan Tamil refugees in India, the government is sending a message to the Tamil people that it is not going to gloss over the past. The indications are that the government is sequencing its responses to problems arising from the past. The government faces a range of urgent challenges, some inherited from previous governments, such as war era human rights concerns, and others that have arisen more recently after it took office. The most impactful of these crises are not of its own making. Global economic instability has affected Sri Lanka significantly. The Middle East war has contributed to a shortage of essential fuels and fertilizers worldwide. Sri Lanka is particularly vulnerable to rising fuel prices. Just months prior to these global pressures, Sri Lanka faced severe climate related shocks, including being hit by a cyclone that led to floods and landslides across multiple districts and caused loss of life and extensive damage to property and livelihoods.

From the beginning of its term, the government has been compelled to prioritise economic recovery and corruption linked to the economy, which were central to its electoral mandate. As the International Monetary Fund has emphasised, Sri Lanka must continue reforms to restore macroeconomic stability, reduce debt vulnerabilities and strengthen governance. The economic problems that the government must address are urgent and affect all communities, whether in the north or south, and across Sinhalese, Tamil and Muslim populations. These problems cannot be postponed. However, issues such as dealing with the past, holding provincial council elections and reforming the constitution are not experienced as equally urgent by the majority, even though they are of deep importance to minorities. Indeed, the provincial council system was designed to address the concerns of the minorities and a solution to their problems.

Unresolved grievances tend to reappear in new forms when not addressed through political processes. Therefore, they need to be addressed sooner rather than later, even if they are not the most immediate priorities for the government. It must not be forgotten that the ethnic conflict and the three decade long war it generated was the single most destructive blow to the country, greatly diminishing its prospects for rapid economic development. Prolonged conflict reduced investment, diverted public expenditure and weakened institutions. If Sri Lanka’s early leaders had been able to negotiate peacefully and resolve their differences, the country might have fulfilled predictions that it could become the “Switzerland of the East.”

Present Opportunity

The present government has a rare opportunity to address the issues of the past in a way that ensures long term peace and justice. It has a two thirds majority in parliament, giving it the constitutional space to undertake significant reforms. It has also demonstrated a more inclusive approach to ethnic and religious minorities than many earlier governments which either mobilized ethnic nationalism for its own purposes or feared it too much to take political risks to undertake necessary reforms. Public trust in the government, as noted by international observers, remains relatively strong. During her recent visit, IMF Director General Kristalina Georgieva stated that “there is a window of opportunity for Sri Lanka,” noting that public trust in the government provides a foundation for reform.

It also appears that decades of public education on democracy, human rights and coexistence have had positive effects. This education, carried out by civil society organisations over several decades, sometimes in support of government initiatives and more often in the face of government opposition, provides a foundation for political reform aimed at justice and reconciliation. Civil society initiatives, inter-ethnic dialogue and rights-based advocacy have contributed to shaping a more informed public about controversial issues such as power-sharing, federalism and accountability for war crimes. The government would do well to expand the appreciation it has deservedly given to OfERR to other NGOs that have dedicated themselves addressing the ethnic and religious mistrust in the country and creating greater social cohesion.

The challenge for the government is to engage in reconciliation without undue delay, even as other pressures continue to grow. Sequencing is necessary, but indefinite postponement carries risks. If this opportunity for conflict resolution is not taken, it may be a long time before another presents itself. Sri Lanka may then continue to underperform economically, remaining an ethnically divided polity, not in open warfare, but constrained by unresolved tensions. The government’s recent reference to Tamil refugees in India is therefore significant. It shows that even while prioritising urgent economic and global challenges, it has not forgotten the past. Sri Lanka has a government with both the mandate and the capacity to address that past in a manner that secures a more stable and just future for all its people.

Strategic diplomacy at Sea: Reading the signals from Hormuz

Published

on

The unfolding tensions and diplomatic manoeuvres around the Strait of Hormuz offer more than a snapshot of regional instability. They reveal a deeper transformation in global statecraft, one where influence is exercised through calibrated engagement rather than outright confrontation. This is strategic diplomacy in its modern form: restrained, calculated, and layered with competing interests.

At first glance, the current developments may appear as routine diplomatic exchanges aimed at preventing escalation. However, beneath the surface lies a complex web of signalling among major and middle powers. The United States seeks to maintain deterrence without triggering an open conflict. Iran aims to resist pressure while avoiding isolation. Meanwhile, China and India, two rising powers with expanding global interests are navigating the situation with careful precision.

China’s position is anchored in economic pragmatism. As a major importer of Gulf energy, Beijing has a direct stake in ensuring that the Strait of Hormuz remains open and stable. Any disruption would reverberate through its industrial base and global supply chains. Consequently, China advocates de-escalation and diplomatic resolution. Yet, this is not purely altruistic. Stability serves China’s long-term strategic ambitions, including the protection of its Belt and Road investments and maritime routes. At the same time, Beijing remains alert to India’s growing diplomatic footprint in the region. Should India deepen its engagement with Iran and other Gulf actors, it could gradually reshape the strategic balance in areas traditionally influenced by China.

India’s approach, in contrast, reflects a confident and increasingly sophisticated foreign policy. By engaging Iran directly, while maintaining working relationships with Western powers, New Delhi is positioning itself as a credible intermediary. This is not merely about energy security, though that remains a key driver. It is also about strategic autonomy the ability to act independently in a multipolar world. India’s diplomacy signals that it is no longer a passive player but an active shaper of regional outcomes. Its engagement with Iran, particularly in the context of connectivity and trade routes, underscores its intent to secure long-term strategic access while countering potential encirclement.

Iran, for its part, views the situation through the lens of survival and strategic resilience. Years of sanctions and pressure have shaped a cautious but pragmatic diplomatic posture. Engagement with external actors, including India and China, provides Tehran with avenues to ease isolation and assert relevance. However, Iran’s trust deficit remains significant. Its diplomacy is transactional, focused on immediate gains rather than long-term alignment. The current environment offers opportunities for tactical advantage, but Iran is unlikely to make concessions that could compromise its core strategic objectives.

Even actors on the periphery, such as North Korea, are closely observing these developments. Pyongyang interprets global events through a narrow but consistent framework: regime survival through deterrence. The situation around Iran reinforces its belief that leverage, particularly military capability, is a prerequisite for meaningful negotiation. While North Korea is not directly involved, it draws lessons that may shape its own strategic calculations.

What emerges from these varied perspectives is a clear departure from traditional bloc-based geopolitics. The world is moving towards a more fluid and fragmented order, where alignments are temporary and issue-specific. States cooperate on certain matters while competing with others. This creates a dynamic but unpredictable environment, where misinterpretation and miscalculation remain constant risks.

It is within this evolving context that Sri Lanka’s strategic relevance becomes increasingly visible. The recent visit by the US Special Envoy for South and Central Asia, Sergio Gor, to the Colombo Port; is not a routine diplomatic courtesy call. It is a signal. Ports are no longer just commercial gateways; they are strategic assets embedded in global power competition. A visit of this nature underscores how Sri Lanka’s maritime infrastructure is being viewed through a geopolitical lens particularly in relation to sea lane security, logistics, and regional influence.

Such engagements reflect a broader reality: global powers are not only watching the Strait of Hormuz but are also positioning themselves along the wider Indian Ocean network that connects it. Colombo, situated along one of the busiest east–west shipping routes, becomes part of this extended strategic theatre. The presence and interest of external actors in Sri Lanka’s ports highlight an emerging pattern of influence without overt control a hallmark of modern strategic diplomacy.

For Sri Lanka, these developments are far from abstract. The island’s strategic location along major Indian Ocean shipping routes places it at the intersection of these global currents. The Strait of Hormuz is a vital artery for global energy flows, and any disruption would have immediate consequences for Sri Lanka’s economy, particularly in terms of fuel prices and supply stability.

Moreover, Sri Lanka must manage the competing interests of larger powers operating within its vicinity. India’s expanding regional role, China’s entrenched economic presence, and the growing attention from the United States all converge in the Indian Ocean. This requires a careful balancing act. Aligning too closely with any one power risks alienating others, while inaction could leave Sri Lanka vulnerable to external pressures.

The appropriate response lies in adopting a robust foreign policy that engages all major stakeholders while preserving national autonomy. This involves strengthening diplomatic channels, enhancing maritime security capabilities, and investing in strategic foresight. Sri Lanka must also recognise the growing importance of non-traditional security domains, including cyber threats and information warfare, which increasingly accompany geopolitical competition.

Equally important is the need for internal coherence. Effective diplomacy abroad must be supported by institutional strength at home. Policy consistency, professional expertise, and strategic clarity are essential if Sri Lanka is to navigate an increasingly complex international environment.

The situation in the Strait of Hormuz thus serves as both a warning and an opportunity. It highlights the fragility of global systems, but also underscores the potential for skilled diplomacy to manage tensions. For Sri Lanka, the challenge is not merely to observe these developments, but to position itself wisely within them.

In a world where power is no longer exercised solely through force, but through influence and presence, strategic diplomacy becomes not just an option, but a necessity. The nations that succeed will be those that understand this shift now and act with clarity, balance, and foresight.
