China has replaced the most powerful official in its western region of Xinjiang, where ethnic violence left nearly 200 people dead last July.

Wang Lequan, who had served as secretary of the Communist Party in Xinjiang since 1994, was replaced by Zhang Chunxian, state media say.

Mr Wang was appointed to a new post in the Chinese Communist Party.

No reason was given for the move but analysts note there was much public anger over his handling of the riots.

China reported that most of the those killed in the riots were from the Han Chinese community. Order was only restored after soldiers were deployed to the region’s main city, Urumqi.
