China's reaction on Thursday has been damning.
The Chinese government has unswerving determination to defend national sovereignty, security and development interests, implement "one country, two systems" principle and oppose any external force in interfering in Hong Kong affairs, he stressed. It was unclear whether any protesters remained at the university on Friday but police have said arrests are not a priority and anyone found would first be given medical treatment.
Hong Kong authorities have repeatedly warned that the act will hit business interests of the U.S. itself considering that 85,000 USA citizens and entrepreneurs are residing in the city, while 1,344 United States companies are engaged in business activities.
The U.S. laws, which passed both chambers of Congress nearly unanimously, mandate sanctions on Chinese and Hong Kong officials who carry out human rights abuses in Hong Kong, require an annual review of Hong Kong's favorable trade status and prohibit the export to Hong Kong police of certain nonlethal munitions.
As part of it, there will be an annual review.
Le said China will take "countermeasures" in response to the "wrong move" taken by the U.S. and America must bear all the consequences that may ensue, the state-run Xinhua news agency reported.
Trump said in a statement. She claimed that the United States was sending a message that it stands in solidarity with the people of Hong Kong, invoking the bogus "human rights" rhetoric that forms the basis for United States interventions around the world.
"Dear America and dear world, please continue to stand with us, and fight alongside us", he said. Pelosi said she looked forward to its "prompt enforcement"-a sentiment echoed by Rubio".
What's happening in Hong Kong today?
After Trump signed the act into law, China's foreign ministry issued a statement accusing the USA government of "disregarding facts and distorting truth" while meddling in Hong Kong in an attempt to disrupt the "great renewal" of the Chinese nation.
"[The bills] are being enacted in the hope that leaders and representatives of China and Hong Kong will be able to amicably settle their differences, leading to long-term peace and prosperity for all", Mr Trump said.
This brought a furious response from the Washington Post in an editorial board statement at the beginning of the week.
Democratic and Republican politicians applauded the signing of the bills.
"China will try not to let the Hong Kong problem and other tensions affect the trade deal".
Meanwhile, pro-democracy opposition leader, Joshua Wong, urged the police to "retreat" from the campus and "set our trapped protesters free". The new law has stronger language in saying he "shall" sanction them but leaves the president with the authority to determine who qualifies as an offender.
Hong Kong police have completed searches at the Polytechnic University, removing a disturbingly vast arsenal of urban warfare weapons, including firebombs and hazardous liquids, from the recently besieged campus. President Trump previously expressed concerns the legislation could hurt ongoing trade talks with Beijing.
Earlier, the ministry summoned US Ambassador to Chinas Terry Branstad to voice protest against the US Congress passing the law.
Trump signed the legislation despite repeated Chinese warnings that the global community should not interfere in Hong Kong, casting the months-long stand-off as a domestic issue.
The Chinese government last week criticized the measure as one that "neglects facts and truth" and "blatantly interferes in Hong Kong affairs and China's other internal affairs". "We urge the U.S. not to continue going down the wrong path, or China will take countermeasures, and the USA must bear all consequences", it said. "You'd better stay tuned".
"The U.S.is creating a false reality, confusing right and wrong, publicly supporting insane violent criminals in carrying out vandalism, violence against innocent citizens, and disruption to the city's peace".
2019 has been a year of mass social upheaval.
