Xinjiang calm ahead of anniversary of deadly riots
Despite appearances of peace over the capital just a day before July 5 anniversary of deadly violence, grievances among Uygurs still simmer

Four years after deadly ethnic clashes erupted in Xinjiang's Urumqi, the city appeared peaceful amid tightened security - but people's grievances remained.
The centre of the city was closely watched by police and public buses underwent strict security checks on the eve of the July 5 riot anniversary.
Squads of seven or eight People's Armed Police officers patrolled People's Square in central Urumqi yesterday, while others stood in the shade of trees.
In contrast to the scene four years ago, when hundreds of Uygur protesters gathered and chanted slogans, middle-and old-aged residents played cards under the shadows of the trees amid temperatures above 34 degrees Celsius.
Many men, who appeared to be undercover policemen, sat in the front of cars or drove around the square, while looking at passers-by with watchful eyes.
On Nanmen Square - where the then-municipal party boss, Li Zhi , spoke at the top of a police vehicle for nearly two hours on July 7, 2009, begging thousands of angry Han protesters to go home - a billboard advertising patriotism, unity and mutual help had been set up.
A bus stop has been built on the Jiefang South Road where several thousand Han people marched with knives and sticks, seeking revenge on the Uygurs, but were stopped by officers of the People's Armed Police with tear gas. Elderly women wearing red armbands sat on chairs at the bus stop yesterday, watching passers-by, while squads of armed police patrolled the area.
