Tensions over the U.S. military’s downing of a suspected Chinese spy balloon are set to culminate this weekend in Munich, where Secretary of State Antony Blinken and top Chinese diplomat Wang Yi are scheduled to attend a security conference. In recent days, the U.S. and China have been discussing setting up a meeting between Messrs. Blinken and Wang, according to people familiar with the matter. The meeting could take place at the Munich Security Conference, which runs Feb. 17-19, the people said, though they cautioned that nothing had been decided and the negotiations are fluid. Vice President Kamala Harris is set to attend and give a speech on supporting Ukraine, officials said.
