In the other game in the morning session, the United States beat Germany 8-5 for its second win in five games, keeping alive its faint hopes of a top-four finish.
The early fixture schedule had been kind to the Chinese at these Olympics, and Sweden was their first real test. They came up short -- just -- but even in defeat, they showed they will be in for the long haul at these Olympics.
In a nip-and-tuck game, China scored a point in the 10th to take it to an extra end. Sweden skip Niklas Edin played a good takeout with his next-to-last stone to remove two Chinese rocks and then made a draw to the 4-foot ring with his final shot.
It was another narrow win for a world champion team that has carved out a reputation for being the grittiest on the circuit.
"It's the exact same situation as in the worlds last year," Edin said. "We had to play 10 ends in almost all games and it was coming down to one or two points in almost all of them. "That's kind of the game plan now."
Edin said China, which has never won a major tournament but is improving under part-time Canadian coach Marcel Rocque, should no longer be underestimated.
"They could easily have been a team that goes undefeated," Edin said. "They are by far the best team we have played on this ice and some of the top teams need to raise their level to keep up with them."
Ominously, Canada has found its form and its famous energy levels that swept the team through its Olympic trials unbeaten for the first time in the country's storied curling history.
This was the Canadians' third straight win after a sluggish start -- and the roar and fierce fist-pump that skip Brad Jacobs greeted his game-defining four-ender in the 7th end spoke a lot of his current mindset.
"That was the most emotional we have been because that was the biggest shot in our biggest game yet," Jacobs said. "I think we were all kind of waiting to explode in this tournament."
The Ice Cube Curling Center was barely half-full and lacking atmosphere as Russia wasn't playing in the morning session. The raucous home support has been getting to Canada and Jacobs welcomed Friday's serenity.
"It was nice for a change. That crowd is tiring," Jacobs said. "Their cheering is just tiring on you mentally."
Norway plays China in the biggest match of the evening session. Canada has a bye.
The win for the Americans was not without a touch of drama. The U.S. led 8-5 and had the last-rock advantage going into the last end but had a stone pulled when Jared Zezel, of Hibbing, Minn, touched the handle again after releasing it.
The Germans couldn't take advantage, though, and fell to their fifth straight loss.
Another win in the evening, against Russia, is vital for the U.S. (2-3) in its bid to reach the last four.
