The United States has gradually become the biggest threat to world's peace and stability given its response to its own human rights problems, said Chinese Foreign Ministry Spokesperson Hua Chunying on Wednesday.

Hua made the remarks during a regular press briefing when asked for comments regarding the Washington Post's story on a slew of government documents showing Washington's missteps and failures on Afghanistan.

"This report slapped the U.S. hard, whom has long claimed itself to be a protector to human rights and morality," Hua said, adding that she believes this disclosure is just one tiny bit of the U.S. problems in this regards.

In the early 2000s, the U.S. had conducted various attack on Iraq for allegedly finding weapons of mass destruction in the Middle Eastern country, yet apologized after years as its "so-called evidence" at the time was all fake, Hua elaborated. 

The Afghan War is the longest war in the American history with an estimate cost of 1,000 billion U.S. dollars. Countless people from both the United States and Afghanistan lost their lives.

She also recalled the staged evidence by the U.S. government, which showed how people were being treated after the alleged April 7, 2018, chemical weapons attack in Douma. It was later exposed by a BBC producer.

Hua called on the United States to reexamine its own problems and give peace and stability back to the world.
