Chinese Premier Li Keqiang has vowed full implementation of "One Country, Two Systems" in Hong Kong and Macao special administrative regions (SAR), and highlighted the necessity to establish sound legal systems to defend national security in the two SARs.

Li, who made the remarks when delivering a report on the government's work at the third annual session of the 13th National People's Congress (NPC) in Beijing on Friday, also expressed resolute opposition to any form of separatist activity that seeks "Taiwan Independence."

"We fully and faithfully implement the policy of One Country, Two Systems, under which the people of Hong Kong govern Hong Kong and the people of Macao govern Macao, with a high degree of autonomy for both regions," said Li.

Li reiterated the central government's full support to Hong Kong SAR and Macao SAR, vowing to help both better integrate into China's overall development.

The premier highlighted the importance of establishing sound legal systems and enforced mechanisms for safeguarding national security, saying the governments of the two SARs were expected to fulfill their constitutional responsibilities.

Legislators of the 13th NPC will deliberate on a bill reviewing a draft decision of the NPC on establishing and improving the legal system and enforcement mechanisms for Hong Kong SAR to safeguard national security, NPC spokesman Zhang Yesui said Thursday.
