NEW DELHI/HONG KONG (Reuters) - 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 defence 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.
