The Washington Post reports that “Vice President Biden on Tuesday said the United States is ‘deeply concerned’ by China’s move last week to establish an air defense zone over a disputed chain of islands in the East China Sea, but he stopped short of demanding that Beijing withdraw its declaration.”

“Biden blamed China’s action for raising regional tensions with a pair of U.S. allies, Japan and South Korea, which the vice president warned would ‘increase the risk of accidents and miscalculation.’”
