The so-called "Uygur Tribunal," which is set to hold a second set of hearings from Friday, is a lie maker that aims to smear China's Xinjiang Uygur Autonomous Region, Chinese Foreign Ministry spokesperson Zhao Lijian said on Thursday.

The so-called "Uygur Tribunal" has nothing to do with law, justice or truth, Zhao told a daily press briefing, noting that the "tribunal" was set up by anti-China forces, groups and its witness is a terrorist designated by the Chinese government.

Xinjiang's development will only get better despite "the clown's play," Zhao said.
