BEIJING (AP) — U.S. Secretary of State Antony Blinken has kicked off two days of high-stakes diplomatic talks in Beijing aimed at trying to cool exploding U.S.-China tensions that have set many around the world on edge. Blinken was meeting Sunday with Chinese Foreign Minister Qin Gang for an extended discussion to be followed by a working dinner. Despite his presence in the Chinese capital the prospects for any significant breakthrough on the most vexing issues facing the planet’s two largest economies are slim. The trip comes after he postponed plans to visit in February after the shootdown of a Chinese surveillance balloon over the U.S. Blinken is the highest-level American official to visit China since President Joe Biden took office.
