Chinese state media have released new details of the government's case against scholar Ilham Tohti who received a life sentence Tuesday for encouraging separatism in his writings and lectures.

The official Xinhua News Agency reported late Wednesday that prosecutors marshalled 210 pieces of evidence including video of Ilham Tohti's lectures where he proclaimed he wasn't Chinese because he belonged to the Uighur ethnic group.

Xinhua also reported that prosecutors said the scholar publicized a fake opinion poll showing 12 percent of Uighurs supported separating from China.

Defense lawyer Li Fangping responded that his client had only referenced someone else's poll and hadn't uttered the words attributed to him in the Xinhua story about not being Chinese.

Li said his only goal had been stimulating discussing about ethnic relations in China.
