Washington, June 7 : India and the US on Monday firmed up an ambitious roadmap for defence industrial cooperation to accord high priority to various projects for the co-development of military platforms and hardware, a move that comes against the backdrop of the Ukraine conflict and China's increasing muscle-flexing in the Indo-Pacific region.

The roadmap was finalised during talks between Defence Minister Rajnath Singh and his American counterpart Lloyd Austin, two weeks ahead of Prime Minister Narendra Modi's state visit to Washington.
