NEW DELHI — India has accelerated the domestic and foreign purchase of weapons in the wake of a border clash between Indian and Chinese troops. Sino-Indo relations are suffering after a skirmish with Chinese troops on June 15 in Galwan Valley. India said 20 of its soldiers were killed, as were Chinese soldiers. Chinese officials have not confirmed any casualties. The Defence Acquisition Council on Friday approved a collection of arms procurement projects worth $5.55 billion, including domestic efforts worth $.4.44 billion. DAC is an apex-level body that falls under the purview of the Ministry of Defence. “In the current situation and the need to strengthen the armed forces for the defence of our borders, and in line with our Prime Minister’s clarion call for ‘Atma Nirbhar Bharat’ [self-sufficient India], the DAC, in its meeting of July 2 held under the chairmanship of Defence Minister Rajnath Singh, accorded approval for capital acquisitions of various platforms and equipment required by the Indian armed forces. Proposals for an approximate cost of $5.55 billion were approved,” the MoD said in a statement.
