China's Public Security Minister Meng Jianzhu arrived in Urumqi, capital of northwest China's Xinjiang Uygur Autonomous Region, Friday to direct work to defuse ongoing unrest in the city.

Meng, also a State Councillor, urged local governments and Communist Party of China (CPC) committees at all levels in Xinjiang "to restore social order as soon as possible."

"Maintaining stability is the central task of overriding importance in Xinjiang at the present time," he said in a meeting with local officials.

Meng said the recent syringe attacks, which were premeditated, masterminded and conducted by law-breakers and instigated by ethnic separatist forces, was a continuation of the July 5 violence in the city. He said their purpose was to undermine ethnic unity.

Meng held discussions with Urumqi residents during which he said traffic controls imposed in the city on Thursday aimed to ensure normal social order and asked for their understanding, support and cooperation.

He also warned "those involved in violence, assaults, vandalism, looting and burning, and those who disrupt social order by different means or undermine ethnic unity, shall be punished according to the law without exception, whatever their ethnicity is."
