BEIJING, Oct. 19 (Xinhua) -- Beijing's preparations for the 2008 Summer Olympic Games won't be affected even if there were any personnel change in the organizing body, an official in charge of the Beijing event said on Friday.

"First and foremost, I'm still not aware of any potential personnel change within the BOCOG," said Beijing's vice mayor Liu Jingmin, referring to the Beijing Organizing Committee for the 2008 Olympic Games.

Liu, executive vice president of the committee, said it has formed a "stable leadership mechanism" in the past few years of preparation. "Its leaders have played a positive role," he told journalists on the sidelines of the 17th National Congress of the Communist Party of China.

"Everything is going on as planned," Liu said.
