The name and works of Ai Weiwei have been removed from a show in Shanghai, "15 Years Chinese Contemporary Art Award," about the history of Chinese contemporary art because of pressure from government cultural officials.

Mr. Sigg [former Swiss Ambassador to China] said he was angered to learn minutes before the opening of the show that museum workers had removed Mr. Ai’s name from the lists of winners and jury members painted on a wall.

He said he had considered stopping the show, but without any way to negotiate with Shanghai Municipal Bureau of Culture officials and minutes to go before the start, he instead chose to register his complaints in his opening comments. His mention that one artist couldn’t be included was not translated, he said.
