Britain's 19-year-old women's curling captain led her team to a victory over world champions China on Wednesday, setting up a same-day showdown with Sweden, the defending Olympic gold medalists.

Scottish teenager Eve Muirhead said the 5-4 win over China, the team that shocked the curling world when it triumphed over Sweden last year in the World Championships, made for a superb introduction to competition at the Games.

It was very close game and I think we expected that, in fact to come down to last stone as it did, she told reporters.

You don't know what to expect going into these Games, but that's the first game over and that's good playing. Now we're just moving on to Sweden tonight.

Muirhead, who confessed to early nerves in the Vancouver Olympic Center venue, finessed a tough takeout in the extra end to take a point and win the game.

The Swedish team improved their record to 2-0 in the women's competition after beating Switzerland on Wednesday.

China captain Bingyu Wang -- speaking to reporters for the first time since curling training began at the venue -- said she was pleased with her team's performance, despite the loss.

She said she did not feel extra pressure in the tournament as 2009 world champions. Hers was the first Asian team to win a world curling championship.

That's finished. That's last year's thing. This is the Olympics -- we just want to enjoy it here and hope we can play well, the 25-year-old said.

In late play on Wednesday, China plays Switzerland, who are 0-2.
