Japan and India announced their first defense codevelopment pact during a summit in New Delhi on July 2, 2026, led by Prime Ministers Sanae Takaichi and Narendra Modi.

The agreement marks a major step in deepening security and economic ties between the two Asian powers as they expand cooperation in technology and energy security.

This move strengthens regional stability by creating a shared defense framework that counters external threats.

  • Japan has not previously co-developed defense systems with any Asian nation outside of its existing US alliance framework.
  • India and Japan had signed a historic security cooperation agreement in 2008, but actual defense co-development remained limited until this pact.
  • The port of Kandla, where green ammonia projects are planned, is one of India's largest crude oil terminals on the western coast.
