Diplomatic friction festered between the United States and China on Wednesday as Beijing charged that U.S. high altitude balloons flew over its Xinjiang and Tibet regions and said it would take measures against U.S. entities that undermine Chinese sovereignty.
Washington and Beijing are locked in a tussle over flying objects after the U.S. military this month shot down what it called a Chinese spy balloon over the coast of South Carolina. Beijing says its balloon was a civilian research vessel mistakenly blown off course, and that Washington overreacted.
