Guangzhou, the capital of Guangdong province, will become a major global comprehensive transport center in the next 15 years, said the local government.

The city government unveiled on Thursday 15 year-development plan to build a multi-layer urban rail network, aiming at increasing rail's share of public transportation to 80 percent by 2035.

By building high-speed direct railway networks, travel time between Guangzhou and major cities in the Guangdong-Hong Kong-Macao Greater Bay Area will be shortened to 60 minutes, according to the city's bureau of planning and natural resources.

Meanwhile, travel time in the rail networks between the downtown center of Guangzhou and its suburb areas will be reduced to half an hour.

Two new metro lines will be added, along with an east-west high-speed subway track linking downtown Guangzhou with neighboring Foshan and Dongguan to be built, said the authority.
