China on Wednesday again urged relevant U.S. politicians to immediately stop condoning violent crimes and grossly interfering in Hong Kong affairs, saying any attempt to interfere in China's internal affairs is doomed to fail.

Foreign Ministry spokesperson Hua Chunying made the call in response to U.S. senators Cotton and Romney's recent remarks on Hong Kong. They said China's Communist Party seems to be ready to repress Hong Kong protesters with violence.

"Any attempt to undermine 'One Country, Two Systems' and Hong Kong's prosperity and stability will surely be resolutely opposed by all Chinese people, including the Hong Kong compatriots," Hua warned. 

She said, "The recent protests and demonstrations in Hong Kong have turned into radical, violent behavior that seriously violates the law, undermines security and social order in Hong Kong, and endangers local people's safety, property and normal life."

No responsible government will turn a blind eye to such serious violent crimes, Hua stressed.

"I want to ask these U.S. senators, do you still remember how the American police dealt with the 'Occupy Wall Street' movement in 2011?" said Hua. "If Hong Kong's radical, violent and illegal activities happened in the U.S., what would the American police do?"

The spokesperson criticized the U.S. side for calling black white and talking nothing about the serious consequences of the radical, violent and illegal acts.

She also questioned U.S. politicians' intention toward Hong Kong, saying that some U.S. senators smeared the just actions taken by the Hong Kong police, who have been professional, highly restrained and committed to safeguarding the rule of law and social order.

The central government firmly supports Chief Executive Carrie Lam in leading the Special Administrative Region (SAR) government in accordance with the law. The central government also supports the Hong Kong police in strictly enforcing the law and firmly supports punishing violent criminals under the law, Hua said.

"Chinese people do not believe in fallacy, nor are we afraid of evil forces," she said, adding that "Chinese people do not make trouble, but we are not cowards when involved in trouble."
