The Chinese joined Sweden and Canada in the semifinals while Britain, despite the loss to China, kept its hopes for a medal alive when Norway fell to Denmark on the final day of the round-robin portion of the tournament.
Denmark had only a 3-5 record heading into its meeting with Norway, but pulled off a 5-3 victory.
Norway and Britain thus ended the preliminary phase of the curling event with a 5-4 record, tied for fourth place. They will meet in a tiebreak game on Tuesday to determine the final spot in the semifinals.
Sweden, which finished atop the round-robin tourney with an 8-1 mark, will meet the Norway-Britain winner in the semifinals on Wednesday. China and Canada will tangle in the other semifinal match. Canada, which is the two-time defending Olympic champion in this event, won its last six matches after starting the tournament with a 1-2 mark.
The gold medal will be determined on Friday.
With a semifinal berth awaiting the winner of the game, Britain scored twice in the ninth end to tie China before the Chinese produced a point in the 10th end to win it.
