Xinjiang's top legislator has vowed to speed up passage of local anti-secession bills in the wake of the worst ethnic unrest on the mainland in memory, state media reported. Observers said the move would help provide a formal legal basis to prevent a separatist movement in the restive region. Beijing has blamed the deadly rioting in Urumqi on July 5 on overseas separatist forces, but analysts and Uygurs said the incident was triggered by long-running discontent over Beijing's unfair policies in the region. The violence led to the deaths of 197 people. Eligen Imibakhi, chairman of the Standing Committee of the Xinjiang Regional People's Congress, told Xinhua on Sunday that the legislature had hurried up legislative procedures to 'provide legal support for Xinjiang's war against separatism and crackdown on terrorism'. Toeing the official line, Mr Imibakhi blamed the 'three forces' of separatism, terrorism and extremism at home and abroad for plotting the incident. 'The job of the people's congress is to use the legal platform to ensure the implementation of government policies to maintain Xinjiang's stability, and to support the public security authority's crackdown on terrorist and separatist crimes,' he said. The legislature would also step up efforts to raise the public's awareness, he said. Promotional materials would be translated into Uygur and Kazakh and distributed to farmers and herdsmen in remote areas. Beijing passed an anti-secession law in 2005, primarily to counter Taiwan's pursuit of formal independence. Then, the breakaway island was ruled by former Taiwanese president Chen Shui-bian, who had been pushing for independence. The law says the mainland can use 'non-peaceful means and other necessary measures to protect China's sovereignty and territorial integrity' if all else fails. Ong Yew-kim, a legal expert from China University of Political Science and Law, said the Xinjiang legislature was likely to draft rules and regulations with detailed guidelines on the implementation of the law. 'The law itself is vague, and local authorities will find it hard to implement it without guidelines,' Professor Ong said. 'The police probably still don't know what to do if rioters carry weapons in public. The guidelines could provide an answer.' Officials said the violence was planned and well organised by rioters, who were mostly from areas outside the regional capital, Urumqi. But Uygur residents in the city and overseas groups said the incident began as a peaceful protest against the death of two Uygur workers in Guangdong and turned sour after police violently cracked down on the protest. Nur Bekri, chairman of the regional government, has said police shot dead 12 rioters on July 5.
