China yesterday renewed its opposition to Japan's accommodation of Rebiya Kadeer, the leader of the separatist World Uyghur Congress (WUC).

Deputy Foreign Minister Wu Dawei summoned Japan's ambassador to China, Yuji Miyamoto, and called upon the Japanese government to prevent Kadeer from engaging in anti-Chinese separatist activities while visiting the country, said the Foreign Ministry.

Kadeer is believed to be the mastermind behind the July 5 riot in Urumqi and responsible for a series of protests at Chinese embassies worldwide.
