National legislators will review a draft decision on establishing and improving the legal system in Hong Kong to safeguard national security, Zhang Yesui, spokesman for the 13th National People's Congress, said on Thursday.

The draft decision will be presented as a motion and discussed during the annual meeting of the NPC, China's top legislative body. More details of the decision will be revealed when the meeting begins on Friday.

National security is the bedrock underpinning the stability of the country and serves the fundamental interests of all Chinese people, including Hong Kong compatriots, Zhang said.

Hong Kong is an inseparable part of China, and as the highest organ of State power, it is absolutely necessary for the NPC to improve Hong Kong's legal system and establish enforcement mechanisms to safeguard national security and solidify the "one country, two systems" principle, Zhang added.
