Rockets' center Yao Ming was back on the court for China ahead of the Olympics, scoring 21 points in 28 minutes of action to lead China past Angola 83-74, the Associated Press is reporting.

"Yao lets us really put the pressure on the opposition," China guard Liu Wei said after the opening day of the FIBA Diamond Ball tournament.

Yao made eight of his 10 shots and had five rebounds and was impressive running the court. He showed no sign of the injury to his left foot that ended his NBA season in February and threatened his Olympic participation.
