A group of 20 Chinese Uighurs who fled to Cambodia after ethnic riots in July have been deported back to China. The United Nations refugee agency strongly condemned the deportation, saying Cambodia had committed a grave breach of international refugee law. The decision follows intense pressure by China, which has referred to the group as criminals. Human rights groups have warned that the group is likely to face persecution on return to China. The expulsions came ahead of a visit to Cambodia by Chinese Vice-President Xi Jingping today. There has been no immediate comment from the Chinese foreign ministry.<br/><br/> <br/><br/> <br/>
