The United States and India have held talks about conducting joint naval patrols that a U.S. defense official said could include the disputed South China Sea, a move that would likely anger Beijing, which claims most of the waterway.

Washington wants its regional allies and other Asian nations to take a more united stance against China over the South China Sea, where tensions have spiked in the wake of Beijing's construction of seven man-made islands in the Spratly archipelago.

India and the United States have ramped up military ties in recent years, holding naval exercises in the Indian Ocean that last year involved Japan's Maritime Self-Defense Force.
