The U.S. Senate passed a Hong Kong-related bill on Tuesday in a move that experts predicted will encourage more violence in the already troubled city and seriously damage China-U.S. relations.

They stressed that the Senate's passage of the so-called "Hong Kong Human Rights and Democracy Act of 2019" ignores the basic facts, is an example of double standards and blatantly interferes in China's internal affairs.

This act is in serious violation of international law and a complete smear of the basic norms governing international relations, said Diao Daming, a researcher at the National Institute of Development and Strategy of Renmin University of China.

Wang Honggang, director of the Institute of American Studies at China Institutes of Contemporary International Relations, pointed out that the true purpose of the U.S. is to interfere in Hong Kong's affairs by using the so-called human rights or democracy.

The experts stressed that what the city needs the most is for violence to end and order to be restored as soon as possible.

Jia Qingguo, professor of the School of International Studies at Peking University, said that the act will further inflame violence by encouraging violent criminals and does no good to solve the Hong Kong issues.

The act's passage has also angered leaders of political organizations in Hong Kong.

All acts that are trying to mess up Hong Kong and thwart China's development will end in vain, they said, stressing that the bill has exposed the U.S.' hegemonic mentality.

"The U.S. has always been proud of its human rights, but gun crimes have never stopped in the country, especially campus shootings," an official with the Democratic Alliance for the Betterment and Progress of Hong Kong said.

"How could the U.S. talk about human rights when it itself has failed to protect even the life and property rights of people?" he questioned.
