South Korean short track speedskater Kwak Yoon-gy has questioned the fairness of the refereeing at the Beijing Olympics after China claimed the gold medal in the mixed team relay in chaotic circumstances.

Kwak alleged the refereeing was biased after China got through its semifinal in the mixed team relay on Saturday only after the United States and Russian Olympic Committee (ROC) teams were disqualified for blocking and obstruction.

South Korea, which was among the favorites, was eliminated in a separate race and China went on to triumph in the final to claim the host nation's first gold medal of the Games.
