The US threats of taking action against Chinese tech companies like TikTok have exposed the US' hypocrisy in maintaining so-called freedom and violate the WTO's nondiscrimination principal, a Chinese government official said Monday. 

Chinese Foreign Ministry spokesperson Wang Wenbin said at a routine press conference on Monday that the US government is making presumption of guilt against relevant Chinese companies and are threatening them without providing any proof for their accusations. 

This violates the principles of the market economy and exposes the US' double standards, Wang said. 

"We call on the US to listen to voices of the global community and provide an open, fair and non-discriminatory business environment to entities that are investing in the US," Wang said. 

He also urged the US to stop politicizing economic, trade problems and promoting discriminatory policies. 

At the conference, Wang was asked to comment on US Secretary of State Mike Pompeo's reported comments which say that the US government "will take action in the coming days" on Chinese apps, including TikTok, according to a CNN report.

US President Donald Trump also said on Friday that he will ban TikTok in the US over security concerns, without giving clear explanations why TikTok has triggered national security concerns.
