Ministry of Foreign Affairs of the People's Republic of China

“ It is not legitimate for China to enact national security legislation for Hong Kong or, in other words, to impose it on Hong Kong.
The truth is: The Central Government of China holds the primary and ultimate responsibility for national security, as is the case in any other country. In all countries, unitary and federal alike, the power to legislate on national security rests solely with the central government. And the NPC is the highest organ of state power in China. ”

“ Some separatists even made a public appeal for foreign sanctions against China and invited the US military to Hong Kong. External forces and "Taiwan independence" forces have blatantly ramped up intervention in Hong Kong affairs, which seriously challenges the "one country, two systems" principle, gravely undermines Hong Kong's law and order, and poses real threats to the country's sovereignty, security and development interests. Forceful measures are therefore required to prevent, forestall and punish these acts.
Falsehood #3: The legislation will undermine "one country, two systems". ”
