Rajnath Singh Dissanayake meeting in Colombo on Wednesday produced three defence memoranda and the virtual inauguration of three Bailey Bridges built by the Indian armed forces, turning the Defence Minister's courtesy call on the Sri Lankan President into the working centrepiece of his three day visit.

The two sides exchanged memoranda of understanding on the upgradation of L70 guns for the Sri Lanka Air Force, on academic cooperation between the National Defence Colleges of the two countries, and on cooperation between their cadet corps, according to the Ministry of Defence. All three had been trailed in reporting ahead of the visit and were confirmed only on Wednesday.

Discussions ran across the full spectrum of the bilateral relationship, the ministry said.

Rajnath Singh Dissanayake meeting delivers the air defence gun upgrade

Six L70 guns held by the Sri Lanka Air Force will be upgraded under a Government of India grant. The guns were supplied to Colombo by India in the first place, which makes the memorandum a refresh of an existing holding rather than a fresh transfer, and the upgrade is aimed at the air defence cover around critical assets on the island.

Pre-visit reporting had described the hardware element as a supply of Indian air defence guns. The release settles it as an upgradation package for guns already in Sri Lankan service.

Cadet corps and defence college memoranda formalise the training track

The academic memorandum links the National Defence College in New Delhi with its Sri Lankan counterpart and is meant to carry knowledge sharing between the two institutions on a standing basis. The second brings the National Cadet Corps into a formal youth exchange arrangement with Sri Lanka. Cadets from a spread of countries travel to New Delhi each year for NCC events, and the memorandum places Sri Lankan participation inside a written framework.

Both are institutional rather than operational, and both address the part of the relationship that has run on individual invitations and training slots.

Three Bailey Bridges inaugurated from Colombo

The two leaders also inaugurated three Bailey Bridges virtually during the Rajnath Singh Dissanayake meeting. The bridges were constructed in Sri Lanka by the Indian defence forces, whose engineers have carried out bridging and construction work on the island before.

Cyclone Ditwah relief and the first responder line

Dissanayake thanked India for the relief mounted under Operation Sagar Bandhu during Cyclone Ditwah and for the rehabilitation package New Delhi extended for reconstruction work across parts of the island, the ministry said. Singh's reply was the sharpest formulation of the day. India considered such assistance "not a favour, but a responsibility" as the closest friend and neighbour of Sri Lanka, he said, and would keep acting as first responder.

The President, welcoming Singh, recalled his own interactions with Prime Minister Narendra Modi and said Sri Lanka would never allow its territory to be used for any activity inimical to India's security interests. That assurance has been the load bearing sentence in Indian readouts of the relationship for several years, and Colombo repeated it here at the level of the head of state.

Singh conveyed greetings on behalf of Prime Minister Modi.

Both sides reaffirmed that as civilisational twins, close neighbours and maritime partners, the two countries would keep working for their development and the welfare of their people while jointly ensuring the safety, security, peace and prosperity of the region. The Defence Minister said the friendship between the two publics rests on historical and civilisational links and on people to people exchanges.

Second day of a visit that had already broken a 38 year gap

Singh arrived in Colombo on Tuesday for a visit running through Thursday, and opened it with an address to the Indian community in the Sri Lankan capital. It is the first standalone trip to the island nation by an Indian Defence Minister in 38 years, a gap this publication traced to KC Pant's 1988 visit when the dates were announced. Defence Minister level travel had been the missing rung in an otherwise dense bilateral calendar.

Underneath the leadership calls sits a review of the India Sri Lanka Defence Cooperation Memorandum of Understanding, signed in Colombo during Prime Minister Modi's visit on April 5, 2025. That was the first umbrella defence agreement between the two countries. The April 2025 package also carried agreements on energy and trade. Wednesday's three memoranda are the first instruments concluded under that framework at ministerial level.

Service level contacts behind the visit

Vice Adm Damian Fernando, Commander of the Sri Lanka Navy, was in India in late August on his first official visit abroad since taking charge, and met Gen NS Raja Subramani, Chief of Defence Staff, in New Delhi for talks on joint training and capacity enhancement. Maritime security has been the steadiest strand of the relationship, carried by the SLINEX naval exercise, the Mitra Shakti army drill and coast guard cooperation in the waters between the two countries.

Singh is still to meet Prime Minister Harini Amarasuriya and Secretary to the Ministry of Defence Air Vice Marshal (Retd) Sampath Thuyacontha, besides Sri Lanka's tri service commanders. The Ministry of Defence account of Wednesday's call names no further signature for the remaining day, and the delegation, drawn from the ministry and the Ministry of External Affairs, leaves on Thursday.
