China's top legislature reviewed a draft law on safeguarding national security in the Hong Kong Special Administrative Region of the People's Republic of China.

The draft law was submitted for deliberation at the 19th session of the Standing Committee of the 13th National People's Congress (NPC) from June 18-20.
