India and Vietnam put co-production of Indian weapons on the official list

External Affairs Minister S. Jaishankar and Vietnamese foreign minister Le Hoai Trung used the 19th India-Vietnam Joint Commission Meeting in New Delhi on 14 September to put co-production of Indian defence equipment on the official list of next steps. The meeting was the first Joint Commission in three years and the first since the relationship was raised to an Enhanced Comprehensive Strategic Partnership during To Lam's state visit in May 2026. The two sides also set 2027 as the Year of India-Vietnam Friendship, the 55th year of diplomatic ties.

Defence supply until now has been gifts and credit. India handed over the missile corvette INS Kirpan in July 2023. Larsen and Toubro built 12 high-speed guard boats under a $100 million line of credit and delivered them in June 2022. Two further lines, $120 million and $180 million, were signed between Exim Bank and Vietnam's finance ministry in July 2024 and are still being drawn. A letter of intent on defence-industry collaboration and a framework for submarine search and rescue already exist. Co-production changes the structure. Vietnam would be making Indian systems, not only receiving them.

The constraint is inventory. Vietnam's navy and air force still run on Russian hulls and airframes, Kilo-class submarines and Su-30 fighters among them. Indian platforms do not drop into that fleet without integration work. The practical starting points are the segments Indian yards already know: patrol craft, sensors, spares for Russian-origin equipment, and the boats already built on Indian credit. The Joint Commission text did not name a first platform. It named the principle.

Trade sat beside defence. The ministers listed market access for Indian marine products, farm goods and pharmaceuticals, plus financial, port and air links, nuclear energy, space, heritage conservation and seafarer standards. Vietnam's place in the Indo-Pacific Oceans Initiative was noted. The South China Sea was in the room even when the communique used the wider phrase Indo-Pacific. Both capitals treat Chinese maritime pressure as the shared problem that makes a defence-industrial relationship worth the friction of export controls and technology release.

A Joint Commission is not a contract. No quantity, no factory, no timeline for a first co-produced hull left New Delhi on Monday. What left was a political instruction to the two defence bureaucracies to stop treating the relationship as a one-way transfer. For Indian exporters that instruction is a queue ticket. For Hanoi it is a hedge: another supplier besides Russia and a partner that does not sit in a treaty with Washington.

Lines of credit already in the pipeline will keep delivering boats while co-production talks run. That split is useful for both sides. Hanoi gets hulls on a known schedule. New Delhi gets a factory conversation that can be shown to other ASEAN buyers. The risk is the usual one in defence industry diplomacy: an announced heading that sits in a drawer until a budget line appears in both capitals in the same year.

Watch the next working-group memo for a named item. Until a hull number or a missile variant appears, co-production is a heading. After Monday it is an agreed heading, which is further than the relationship has been willing to write down.

Jaishankar and Trung also used the session to compare notes on West Asia. That comparison is now part of the same file as patrol boats. India is selling itself in Southeast Asia as a defence manufacturer. Vietnam is testing whether that claim includes production on Vietnamese soil. The 19th Joint Commission put the test on paper.
