Xinjiang needs careful study

Ethnic tensions in the far western autonomous region of Xinjiang have again flared into violence. In the worst single incident since rioting between Muslim Uygurs and Han Chinese six years ago left 197 people dead, last week 15 community workers and police were among 21 killed in a clash involving knives, axes and the burning down of a house.
