BEIJING, March 20 (Xinhua) -- China will soon unveil and implement a plan for building the Guangdong-Hong Kong-Macao Greater Bay Area to promote regional development, Premier Li Keqiang said Tuesday.

The Guangdong-Hong Kong-Macao area can be built into a world-class Greater Bay Area because each of the three areas can complement each other with their own unique strength, Li told a press conference following the conclusion of the annual legislative session.

The plan is being formulated and will be made public soon for implementation, according to Li.

The premier said the plan would gradually enable residents in Hong Kong and Macao special administrative regions to enjoy equal access to housing, education and transportation once they live and work in the mainland, especially in Guangdong Province.

While encouraging Hong Kong and Macao to integrate their development plans with that of the mainland, the central government will continue to uphold the principles of "one country, two systems," and "Hong Kong people administering Hong Kong" and "Macao people administering Macao" with a high degree of autonomy, he noted.
