China ended South Korea's winning streak in the Olympic women's short-track 3,000-metre relay with a world record time at the Vancouver Games.
South Korea finished first in the final but they were disqualified after referees ruled that Kim Min-Jung impeded Sun Linlin's path after a handover with six laps to go.
Canada took the silver and the bronze went to the United States.

Led by newly-crowned Olympic champions Wang Meng (500m) and Zhou Yang (1,500m), China clocked 4min 06.61sec, breaking their own world record of 4:07.179 set in Salt Lake City in October 2008.
South Korea, the most medaled nation in the Olympic short-track competition since the sport's debut in 1992, had reigned supreme in the event since a young squad dethroned Canada in 1994.
But China beat South Korea into second spot when they won their eighth world 3,000m relay title last year. They have since won three out of the season's four World Cup relays and South Korea one.
After China took an early lead, they battled with South Korea until the controversial handover.
South Korea kept the Chinese at a safe distance toward the finish and celebrated on the oval until the referee disqualified them.
