China decided on Monday to take a series of actions in response to the United States's move of signing the so-called Hong Kong Human Rights and Democracy Act of 2019 into law, Chinese Foreign Ministry spokesperson Hua Chunying said.

Denouncing the passing of the bill as a severe interference in China's internal affairs and a serious violation of international law, Hua said Beijing will suspend the review of the request for U.S. maritime vessels visiting Hong Kong and sanction several U.S. non-governmental organizations (NGO), effective Monday. The list includes the National Endowment for Democracy (NED), National Democratic Institute (NDI) for International Affairs, International Republican Institute, Human Rights Watch, and Freedom House.

"This is the price they are paying for destroying Hong Kong's peace and stability," she stressed, referring to facts and evidence that showed U.S. NGOs' backing anti-Beijing activists in Hong Kong, funding 'pro-independence' protests and inciting acts of extreme violence and crimes.

The NED, one of the U.S. NGOs to be sanctioned, though defines itself as a private, non-profit organization committed to supporting democratic institutions worldwide, has been proved covert ties with Central Intelligence Agency (CIA), which operates two of its largest overseas branches in Hong Kong, one of which - NDI - is also on the sanction list.

China will take further, necessary countermeasures, as the situation develops, to safeguard its national sovereignty, security and development interests, Hua said, urging the U.S. side to get back to the right track and keep its dirty hands off Hong Kong, which is Beijing's internal affairs.  

Radical protests have been wreaking havoc in Hong Kong since June, at times forcing businesses, government institutions, schools and even the international airport to shut down.

The city was partly paralyzed and violence flared as anti-government protesters rampantly smashed facilities, set fire, assaulted innocent civilians, trampled on the rule of law, and jeopardized social order.

Beijing has repeatedly condemned foreign interference in its internal affairs, as U.S. officials were seen meeting with several radical opposition figures, including the "Hong Kong independence" activist Joshua Wong. 

Also, in June, U.S. Speaker of the House Nancy Pelosi publicly stated that Hong Kong demonstrations were "a beautiful landscape," and part of congressmen raked up the so-called "Hong Kong Human Rights and Democracy Act". Then in July, Pence and U.S. National Security Advisor John Bolton held meetings with Hong Kong opposition leaders.

Beyond that, more American faces appeared in Hong Kong violent demonstration scenes from media exposed pictures, let alone the figure of the American flag.
