BEIJING - China is reluctant to predict its gold medal tally at the upcoming IAAF World Championships in Daegu, South Korea, although former Olympic and world champion hurdler Liu Xiang should be prominent on the world stage again.

"Our goal is to win two to three medals in Daegu. But it is difficult to figure out the color of the medals," said Feng Shuyong, head coach of the Chinese athletics team, before heading to Daegu.

Although he has fully recovered from a foot injury, which forced him to withdraw from the first round of the 110m hurdles at the Beijing Olympic Games, Liu, the former world record holder, will face strong challenges from several rivals.
