What Happened
- Sri Lanka's President Anura Kumara Dissanayake confirmed that his government denied docking permission to the Iranian frigate IRIS Dena and simultaneously refused a US request to land two armed warplanes at Mattala Rajapaksa International Airport.
- Dissanayake framed the twin refusals as a demonstration of strict neutrality: "There were two pieces of paper on our desk; one asked for permission for Iranian vessels... other for 2 US warplanes. As neutral nation we said no to both. That's impartiality."
- The US had requested permission to land two warplanes armed with eight anti-ship missiles from its base in Djibouti at Mattala Airport from March 4 to 8; the Iranian request was for three warships to make a port call from March 9 to 13.
- The IRIS Dena was later sunk by the US Navy submarine USS Charlotte in international waters approximately 19 nautical miles off Galle, Sri Lanka; Sri Lanka subsequently repatriated the remains of 84 Iranian sailors killed in the attack.
- Colombo's refusal was met with US envoy Sergio Gor, with whom Dissanayake continued diplomatic engagement despite the denial.

The Hague Conventions and Neutrality in Naval War
The Hague Conventions of 1899 and 1907 are among the earliest formal statements of the laws of war in international law, establishing rules for warfare and the rights and obligations of neutral states. The 1907 Convention XIII specifically governs the rights and duties of neutral powers in naval war, setting out exactly the kind of situation Sri Lanka faced.
- Convention XIII (Hague, 1907) restricts belligerent warships from remaining in neutral ports for more than 24 hours, except in cases of damage or stress of weather.
- The maximum number of warships belonging to a single belligerent permitted simultaneously in a neutral port is three.
- Neutral states must treat all belligerents equally — if they permit one side's warships, they must permit the other's on equal terms.
- Allowing belligerent military aircraft or armed warplanes to land at neutral territory airports would similarly compromise neutrality.
- The Hague Conventions entered into force on January 26, 1910.
Connection to this news: Sri Lanka's simultaneous denial to both Iran and the US was a legally grounded application of Hague Convention neutrality principles — treating both belligerents equally and refusing to allow either side to use its territory as a military staging point.
Non-Alignment and Strategic Autonomy as Foreign Policy Doctrine
Non-Alignment is a foreign policy doctrine by which a state avoids formal military alliances with major power blocs, preserving the freedom to engage with all parties on the basis of mutual interest. It was a foundational principle of post-colonial states and is codified in the Non-Aligned Movement (NAM), of which Sri Lanka is a founding member.
- Non-Aligned Movement (NAM) was formally established at the Belgrade Conference in 1961; founding members included India, Yugoslavia, Egypt, Indonesia, and Ghana.
- Five Principles of Peaceful Coexistence (Panchsheel, 1954): mutual respect for sovereignty and territorial integrity, mutual non-aggression, non-interference in internal affairs, equality and mutual benefit, peaceful coexistence.
- Sri Lanka's neutrality in the 2026 conflict reflects both NAM principles and the practical imperatives of a small island nation strategically located in the Indian Ocean, adjacent to a major global shipping lane.
- India is also a founding member of NAM and has consistently upheld strategic autonomy as a core foreign policy principle.
Connection to this news: Sri Lanka's refusal demonstrates that non-alignment remains a living doctrine for small states navigating great-power competition, particularly when located at strategically vital positions like the Indian Ocean.
Mattala Rajapaksa International Airport and Sri Lanka's Strategic Geography
Sri Lanka's Indian Ocean location places it at one of the world's busiest maritime chokepoints. The country sits astride the major east-west shipping lanes connecting Europe/Middle East with East Asia. Mattala Rajapaksa International Airport in Hambantota, southern Sri Lanka, is significant because of its proximity to this shipping lane and its location near the Hambantota Port — itself leased to China (China Merchants Port Holdings) for 99 years since 2017.
- Mattala Rajapaksa International Airport: located in Hambantota district, southern Sri Lanka, opened in 2012.
- Hambantota Port: leased to China Merchants Port Holdings for 99 years in 2017 — a frequently cited example of "debt-trap diplomacy" in global geopolitical discourse.
- The US request to land armed warplanes at Mattala (adjacent to China's leased port) had additional geopolitical layering beyond the Iran conflict alone.
- Sri Lanka is flanked by two major powers with stakes in the Indian Ocean — India and China — while also being pressed by the US; its neutrality serves as a balancing act across all three.
Connection to this news: The choice of Mattala Airport for the US request was strategically significant given its proximity to the Chinese-leased Hambantota Port, adding another dimension to Sri Lanka's neutrality calculus.
