BEIJING (Xinhua): China has warned the United States if it continues to play double standards on anti-terrorism or try to infringe upon other countries' sovereignty and security, it will end up swallowing a bitter fruit with its own interests harmed.

"It hasn't been long since the Sept. 11 attacks. The U.S. should not forget the pain as wounds heal," Foreign Ministry spokesperson Hua Chunying said at a press conference on Wednesday.

The U.S. House of Representatives has just passed the so-called "Uyghur Human Rights Policy Act of 2019". U.S. Representative Chris Smith called the Chinese government's preventive counter-terrorism and deradicalization efforts in Xinjiang "modern-day concentration camps." U.S. House Speaker Nancy Pelosi called the efforts "an outrage to the collective conscience of the world."

Responding to the U.S. moves and comments, Hua said Xinjiang-related issues are by no means about human rights, ethnicity or religion, but about "the fight against separatism and violent terrorism".

Since the 1990s, especially after the Sept. 11 attacks, elements of terrorism, separatism and extremism forces launched several thousand violent terrorist attacks in Xinjiang, causing massive casualties as well as property loss, she said, noting that in the "July 5" incident in 2009 alone, 197 people were killed and more than 1,700 injured.
