Is China ready to go head-to-head against Team USA on the track?

Liu Xiang will be the centerpiece of the country's track and field campaign.

The 2004 Olympics champion hurdler clocked a wind-assisted 12.97 sec result at the Eugene, Oregon, meet last month, matching Dayron Robles' world record time, as he looks to atone for Beijing, where he withdrew from the race in front of a disappointed home crowd due to a heel injury.

Although American Aries Merritt recorded a season-best time of 12.93 to win the US Trials this month (Liu's Eugene result didn't count because of the tailwind), the Shanghai native remains the favorite.

Still, head track and field coach Feng Shuyong warned of the foreign challenges, including the enigmatic Robles.

"People think Liu will have no problem winning because all of his major opponents have not performed better than him (this season)," Feng said. "But that's not true. Robles is still young and he is the man who has run under 13 seconds the most times. He is still dangerous."

Women's discus thrower Li Yanfeng will join Liu as another gold medal hope after winning the country's only title at the Worlds last year.

Medals could also be won in six other events, including the women's marathon, shot put, hammer and men's race walk, Feng said.
