Security cameras are seen (R) on a street in Urumqi, capital of China's Xinjiang region on July 2, 2010 ahead of the first anniversary of bloody violence that erupted between the region's Muslim ethnic Uighurs and members of China's majority Han ethnicity. Police have installed 40,000 security cameras in more than 3,000 public buses, 200 bus stations, along more than 4,000 roads, 270 schools and more than 100 large supermarkets or malls, the Xinjiang Economic Daily said.
