"I am deeply concerned that the 22 January trial of Chinese legal scholar Xu Zhiyong and the prosecution of other good-governance advocates are retribution for their public campaigns to expose official corruption and for the peaceful expression of their views," Ambassador Mr Locke said in a statement.
"The United States government calls on Chinese authorities to release Xu and other political prisoners immediately, to cease any restrictions on their freedom of movement, and to guarantee them the protections and freedoms to which they are entitled under China's international human rights commitments."
The BBC reports that Gary Locke, the U.S. Ambassador to China and former U.S. Commerce Secretary has demanded that China release Xu Zhiyong, the founder of the movement from custody. Read Locke's statement below:
