Tong, who just arrived here with her teammates, looked relaxed with a big smile on her face. She said she did not know that her major rival, Japan's Olympic judo gold medalist Maki Tsukada has quit from the Games.

Tong said she doesn't know of Tateyama, saying that she will play her own way in the competition.

Japanese officials allegedly said Japan would sweep all women's judo gold medals in the Doha Games.
