Across the country, China is seeing a resurgence of local ethnicity and culture, most notably among southerners such as the Cantonese and Hakka, who are now classified as Han.

For centuries, China has held together a vast multi-cultural and multi-ethnic nation despite alternating periods of political centralization and fragmentation. But cultural and linguistic cleavages could worsen in a China weakened by internal strife, an economic downturn, uneven growth, or a struggle over future political succession.

The initial brawl between workers in a Guangdong toy factory, which left at least two Uighur dead on 25 June, prompted the mass unrest in Xinjiang on 5 July, which ended with 156 dead, thousands injured, and 1500 arrested, with on-going violence spreading throughout the region.

The National Day celebrations scheduled for October 2009, seeks to highlight 60 years of the “harmonious” leadership of the Communist Party in China, and like the 2008 Olympics, its enormous success. The rioting threatens to de-rail these celebrations.

Officially, China is made up of 56 nationalities: one majority nationality, the Han, and 55 minority groups. The 2000 census revealed a total official minority population of nearly 104m, or approximately 9% of the total population.
