Hurdler Liu Xiang stated his full recovery from a stunning Beijing Olympics exit as the Asian Games Wednesday saw a second doping case and China's new record on medal tally.

The former world record holder, hitting the track at only his second event in a year, extended his lead over the last four hurdles to snatch the men's 110m hurdles gold medal in his season best 13.09 seconds.

His Chinese teammate and Athletes' village roommate Shi Dongpeng took silver in 13.38.

Carrying a nation's expectations, Liu limped off two years ago with an Achilles injury before even starting his first heat at the Beijing Games, leaving the whole Bird's Nest stadium in stunned silence.

Liu's only other impressive result after comeback was at a September 2009 meet in Shanghai where he timed 13.15 seconds.

"I am very happy to win the Asian Games title the third time," said the 27-year-old former Olympic and world champion after Wednesday's gold-winning final. "I didn't expect I could race in 13.09."

What was truly unexpected on Wednesday was that the Olympic Council of Asia revealed a second doping scandal, which involved a second Uzbek athlete.

Jakhongir Muminov, a Greco-Roman 84kg division wrestler, tested positive for Methylhexaneamine in an out-of-competition doping test on Nov. 19, OCA medical committee chairman Dr. Mani Jegathesan told press.

In the Games' first doping case, Uzbekistan's judoka Shokir Muminov was stripped of his silver medal last Friday after testing positive for the same banned stimulant.
