India and the United States are in talks to help each other track submarines in the Indian Ocean, military officials say, a move that could further tighten defense ties between New Delhi and Washington as China steps up its undersea activities.
Both the United States and India are growing concerned at the reach and ambition of the Chinese navy, which is taking an increasingly assertive stance in the South China Sea and is challenging India's domination in the Indian Ocean.
New Delhi, shedding its decades-old reluctance to be drawn into America's embrace, agreed last month to open up its military bases to the United States in exchange for access to weapons technology to help it narrow the gap with China.
