China threatens to retaliate over U.S. bill that could shutter Hong Kong trade offices

American lawmakers have passed a bipartisan bill that could eventually lead to the shuttering of Hong Kong's U.S.-based trade offices, drawing strong condemnation from the Chinese-ruled city and Beijing. 

The legislation, the Hong Kong Economic and Trade Office Certification (HKETO) Act, was passed by the U.S. House of Representatives with overwhelming support on Tuesday.  

If it clears the Senate and is signed into law, HKETO would require the U.S. secretary of state to annually review the "privileges, exemptions and immunities" granted to Hong Kong's Economic and Trade Offices.

And if the secretary of state determines an office to no longer enjoy a "high degree of autonomy" from the Chinese government or to pose other concerns, such as those related to national security, it will be required to terminate operations. 

Beijing strongly condemned the act's passing on Wednesday, accusing the U.S. of politicizing normal economic cooperation and attempting to contain Hong Kong's development. 

"China urges the U.S. to stop advancing that act to prevent further damage to the stability and growth of China-US relations. Otherwise, China will take strong and resolute countermeasures," a government spokesperson said.

The remarks echoed a statement from the Hong Kong government that decried the U.S. for twisting facts, violating international laws and norms, and grossly interfering in the affairs of Hong Kong. 

Hong Kong has operated as a special administrative region of China since a handover from the British in 1997.
