TWO upcoming concerts in China by American rock group Bon Jovi have been suddenly cancelled, reports said Tuesday. 

Bon Jovi was scheduled to play two dates -- in Beijing and  Shanghai -- but ticket sales were abruptly halted with no reason given and the performances scrapped, according to local blogs.

The ticket sellers Damai.cn confirmed that they had stopped selling tickets at the behest of the concert organizers, but were not told why.
