It was also "dangerous" to politicize the Olympics in the long run, said Liu Guijin, special representative of the Chinese government to Darfur issue, said at a news conference held at the Chinese Embassy in London.

Liu told reporters that he was very surprised by Oscar-winning film director Steven Spielberg's resignation as an artistic adviser to the 2008 Beijing Olympics.
