The government and people of China firmly oppose the signing of the so-called Hong Kong Human Rights and Democracy Act by the United States, the Foreign Ministry said on Thursday, calling the move bullying.

Signing the bill into law severely meddles in Hong Kong affairs, severely interferes in China's internal matters and seriously violates international laws and basic norms governing international relations, the ministry said in a statement released on its website.

The intention of the US side is very vicious by bolstering violent criminals who smashed facilities, attacked innocent residents, trampled on the rule of law and social order, the ministry said.

The ministry said that the fundamental purpose of the US side is to destroy Hong Kong's prosperity and stability, undermine the great practice of "one country, two systems" and barricading the historical process of realizing the great rejuvenation of the Chinese nation.

China sternly warn the US side that Hong Kong is China's Hong Kong and Hong Kong affairs are China's internal matters that allow no interference from foreign governments or forces, it said.

The so-called act will only make the Chinese people including Hong Kong compatriots to clearly see the vicious intentions and hegemony of the US, it said, noting that the Chinese people will be more united and the attempt of the US is doomed to fail.

The ministry reaffirmed that the Chinese government is determined in opposing foreign interference in Hong Kong affairs, implementing the "one country, two systems" principle and safeguarding national sovereignty, security and development interests.

It urged the US side not to go its own way, otherwise, the Chinese side will absolutely take resolute countermeasures and the US side will bear all the consequences.
