Authorities in Guangdong province will accelerate infrastructure development in coming years, according to the southern province's governor.

Zhu Xiaodan said work will be speeded up in Nansha in Guangzhou, Qianhai in Shenzhen and Hengqin in Zhuhai.

"The three areas will become key platforms for further economic cooperation between Guangdong and the special administrative regions of Hong Kong and Macao," Zhu said during the annual session of the National People's Congress.
