The U.S. military said two of its warships sailed near islands claimed by China in the South China Sea on Monday, a move that could anger Beijing at a time of tense relations between the world’s two biggest economies.
The South China Sea is one of a growing number of flashpoints in the U.S.-China relationship, which also include a trade war, U.S. sanctions and Taiwan.
President Donald Trump dramatically increased pressure on China to reach a trade deal by announcing on Sunday he would hike U.S. tariffs on $200 billion worth of Chinese goods this week and target hundreds of billions more soon.
