In a unanimous vote on Tuesday, the Senate passed the "Hong Kong Human Rights and Democracy Act," showing full support for Hong Kong protesters as well as a warning to China against violent suppressions.
Under the bill, the United States would need to certify at least once a year that Hong Kong retains enough autonomy to qualify for special U.S. trading considerations.
Washington could also place sanctions on officials responsible for human rights violations in Hong Kong.
Tuesday's vote marks a new challenge to the Chinese government, as Washington and Beijing are still tied up in a prolonged trade war.
The bill will now go to the House of Representatives.
As the bill is slightly different from one passed unanimously by the House last month,
the two chambers will narrow their differences before sending the bill to President Trump.
Beijing responded by again telling the U.S. to not interfere in its domestic affairs.
"Its behavior only exposes its ulterior intention to intervene in Hong Kong and its double standards on violent crimes. To compare the efforts of the Hong Kong police in properly enforcing the law and stopping violence and riots with the radical violent behavior of the extremist forces is, in nature, an insult to the rule of law and human rights."
China vowed strong counter-measures to safeguard its sovereignty and security, warning that the negative consequences will end up coming back to the U.S.
