Rental apartment market explodes in Greater Bay Area

China's major real estate developers are racing to open more rental apartments in the Guangdong-Hong Kong-Macao Greater Bay Area, but industry insiders warned of oversupply.

As the national development plan of the GBA is about to be unveiled soon, more companies and professionals are swarming the area.

It currently has a population of about 70 million, accounting for 5 percent of the nation's total, but it is estimated to reach 10 percent in the future.
