The US Senate has unanimously passed the Hong Kong Human Rights and Democracy Act.
The bill passed Tuesday in a voice vote. It aims to protect human rights in Hong Kong as China cracks down on a democracy movement in the territory that began in June.
The bill will now move to the House of Representatives. The two chambers will then agree on a final version of the bill before submitting it to President Donald Trump for approval.
On Wednesday, President Tsai Ing-wen called the situation in Hong Kong disturbing and said that there is a humanitarian crisis there.
China has responded by accusing Washington of interfering in its domestic affairs and of holding double standards. The Chinese foreign ministry has strongly condemned the bill and demanded that Washington take immediate steps to stop its progress.
A spokesperson for the Hong Kong government has also called the bill extremely regrettable.
