China on Wednesday condemned U.S. Secretary of State Mike Pompeo's false remarks on China's treatment of people from Uygur ethnic group in northwestern China's Xinjiang Uygur Autonomous Region, urging U.S. politicians to get rid of their bias and double standards on China's internal affairs. 

"The Xinjiang issue is not about human rights or religious freedom, it is about China's counter-terrorism and de-radicalization efforts there," Chinese Foreign Ministry spokesperson Geng Shuang said during a regular press conference in Beijing, expressing strong opposition against repeated demonization and politicization of the issue.

Pompeo, who has repeatedly accused China of running so-called "detention camps" in Xinjiang, said on Tuesday in a statement that "the U.S. is deeply troubled by reports of China harassing families of Uygur activists."

Refuting Pompeo's words as "malicious slander," Geng said that China's governance in the region has been proven effective in the prevention of extremism and terrorism, and has also made great contributions to the global cause of counter-terrorism.

"China, not by launching a physical war, but by setting up vocational education and training centers, has seen the return of safety and security to Xinjiang," he said, noting there has not been a single terrorist attack in the region in the past three years and the fundamental human rights of people of all ethnic groups are safeguarded in the country.
