In China, athletes have the right to choose their province of registration. Many, understandably, turn to those provinces that promise to provide the best financial, medical and technical support.

Zhang and Yunnan were in a honeymoon phase after the Athens Olympics. But it did not last long, as Zhang failed to win even the national championship in 2005.

"The contract expired last year. I have not taken any salary or training allowance since then. I have nothing to do with Yunnan right now," Zhang said.

"I signed with Shanxi, which has been approved by the administrative center. Shanxi's promise convinced me to move."

Zhang, now 33, made a strong return in September after winning the world title in the 69kg class. He has once again emerged as a gold-medal contender for the Beijing Olympics.

"I represented Shanxi when I won the world championships in September. I know the prime time of career was closely linked to Yunnan. But it's a trade agreement and it's now over (with Yunnan)."

The final result is yet to be ruled on by the SGAS, but the rift has disrupted Zhang's training schedule.

"I am almost devastated. My daily training is badly affected. I just hope it'll be settled as soon as possible," Zhang said. "I want to be focused on the preparation and reach the best form in the Beijing Olympics."

Ma Wenguang, Director of the Weightlifting, Wrestling and Judo Administrative Center under SGAS said it is a technicality issue and not difficult to deal with.
