Germany, champions in 2003 and 2007, demolished Sweden 4-1 in Ottawa, while China won 1-0 in Edmonton to send the last African challenger Cameroon out of the tournament.

Forwards Celia Sasic and Anja Mittag both scored their fifth goals of the tournament as the top-ranked Germans closed down their fifth-ranked European rivals in scorching conditions at Lansdowne Stadium.

Sasic scored twice with Mittag and Dzsenifer Marozsan also on target to put the favourites through to the last eight for the seventh time in as many editions of the tournament.

Germany coach Silvia Neid described the victory as "a very important game, maybe a key match" in the tournament.

"We haven't had games of this quality in the World Cup apart from Norway, " said Neid, whose group had included minnows Ivory Coast and Thailand.

Germany, who were shocked in the quarter-finals of the 2011 World Cup at home, next play either France or South Korea, who clash in Montreal on Sunday, for a place in the semi-finals.

The 30-year-old Mittag set Germany on their way in the 24th minute with a solo run following a poor pass in the Swedish defence for her fifth goal in four matches.

And 12 minutes later Sasic got her first when she slotted in a contentious penalty awarded for a foul on Mittag inside the box by her former FC Rosengard teammate Amanda Ilestedt.

Sofia Jakobsson nearly pulled one back for the Swedes seconds before half-time but could not manage to keep her header down.

Sasic grabbed her second on 78 minutes when her diving header gave her a fifth goal of the tournament after Simone Laudehr's initial effort had come back off the post.

Defender Linda Sembrant got one back for the Swedes with eight minutes to go, but Marozsan connected with a sliding shot that went over a diving Hedvig Lindahl two minutes from time.

- Touchline ban -

While Germany and Sweden battled in temperatures reaching 38 degrees Celsius (100 Farenheit), it was raining in Edmonton, where Wang Shanshan's first half goal was enough to set up a meeting with either the United States or Colombia for a place in the semi-finals.

China coach Hao Wei had a touchline ban and was forced to watch the game from the stands in Edmonton's Commonwealth Stadium.
