China said on Monday US military ships and aircraft won't be allowed to visit Hong Kong, and also announced sanctions against several US non-government organisations for encouraging protesters to "engage in extremist, violent and criminal acts".
Foreign ministry spokeswoman Hua Chunying said Monday NGOs, including the National Endowment for Democracy, Human Rights Watch, Freedom House, National Democratic Institute and International Republican Institute had acted "badly" during almost six-months of unrest in Hong Kong.
Along with suspending visits by official USA military ships and aircraft, Hua said China would sanction organizations including the National Endowment for Democracy, the National Democratic Institute for International Affairs, Human Rights Watch, the International Republican Institute, Freedom House, and others that she said had "performed badly" in the Hong Kong unrest.
China's United Nations mission in Geneva said the article interfered in China's internal affairs and exerted pressure on Hong Kong's Government and police, which "will only embolden the rioters to conduct more severe radical violence".
The US-headquartered NGOs targeted by Beijing include the National Endowment for Democracy, the National Democratic Institute for International Affairs, the International Republican Institute, Human Rights Watch, and Freedom House.
"They shoulder some responsibility for the chaos in Hong Kong and they should be sanctioned and pay the price", Ms Hua said, without specifying what form the measures would take.
However, it "sends a signal that US-China tensions will continue to deepen", Raska said.
In an opinion piece published Saturday in Hong Kong's South China Morning Post newspaper, Bachelet called for an "independent and impartial judge-led investigation into reports of excessive use of force by the police".
The new law requires Washington to monitor Beijing's actions in Hong Kong. If ever found unsatisfactory, the city's special status for US trading could be tossed.
Hong Kong has seen nearly nonstop protests for six months demanding democratic elections and an investigation into police use of force at the demonstrations.
Hong Kong - a British colony until 1997 - is part of China under a model known as "one country, two systems".
Under this model, Hong Kong has a high degree of autonomy and people have freedoms not seen in mainland China.
Though protests against local authorities about issues such as environmental concerns, city planning and workers' rights occur from time to time, it is rarely on the scale of the Wenlou skirmishes.
So far, only one has been met - the formal removal of a extradition bill that would have allowed people within Hong Kong to be arrested and tried in mainland Chinese courts.
