Participants in the ongoing protests are demanding the democratization of the electoral system, the introduction of direct elections of the head of the Hong Kong administration, the release of all arrested protesters and the investigation of harsh police actions.
The comments were a stern warning to organizations that China believes are affiliated with Washington — and the first salvo in what Beijing has promised will be" forceful" retaliation against the United States for the Hong Kong human rights and democracy activists, which was passed by Congress and signed into law by President Trump last week.
Not immediately clear how the sanctions will affect foundations or corporations that donate funds to nonprofit organizations listed in the blacklist. Few of the groups have staff in mainland China.
Kenneth Roth, Executive Director of Human Rights Watch, said his organization does not receive funding from any government and "regrets" China's announcement of unspecified sanctions.
Human Rights Watch urged all parties to the protests to refrain from violence, he said." Instead of targeting an organization that seeks to protect the rights of the people of Hong Kong, the Chinese government should respect those rights," Roth said.
Freedom House said the threat of sanctions had strengthened its resolve to confront the Chinese government's efforts to undermine human rights. "We do not seek permission from the Communist Party of China to support such legitimate goals," Freedom House President Michael J. Abramovich Bush said in a statement.
Foreign nonprofit workers inside China have long faced suspicion and vulnerability. Michael Kovrig, a former Canadian diplomat, working for the non-governmental International crisis group, was detained last year on national security grounds. He was captured amid a diplomatic dispute between Beijing and Ottawa.
Swede Peter Dahl was detained in 2016 for his role in providing legal aid to a network of Chinese activists that the Communist party deemed subversive.
China passes strict law on involving foreign NGOs in security oversight.
China has stepped up oversight of foreign nonprofits since the adoption of the NGO law in 2016, which gave security officials broad oversight powers.
Last week, Chinese officials revealed for the first time a police investigation conducted under the NGO law. New York-based nonprofit Asia Catalyst, which has worked on HIV-related public health projects in southern China, has been investigated by Beijing police and fined, the foreign ministry announced.
The U.S. regularly criticizes China for violating human rights and religion in the Xinjiang Uighur Autonomous Region, home to Uighurs, Kazakhs and several other people who practice Islam. Earlier, the U.S. banned the export of American goods for 28 Chinese companies and imposed visa restrictions on members of the Chinese government and the Communist Party, which, according to Washington, are involved in the repression. The Chinese Foreign Ministry said that information about" re-education camps" for Uighurs in the Xinjiang Uighur Autonomous region was not accurate.
