U.S. and Chinese officials concluded on Friday what Washington called "tough and direct" talks in Alaska, which laid bare the depth of tensions between the world's two largest economies at the outset of the Biden administration.

The two days of meetings, the first high-level in-person talks since President Joe Biden took office, wrapped up after a rare and fiery kickoff on Thursday when the two sides publicly skewered each others' policies in front of TV cameras.

The talks appeared to yield no diplomatic breakthroughs — as expected — but the bitter rivalry on display suggested the two countries had little common ground to reset relations that have sunk to the lowest level in decades.
