Premier Li Qiang presided over a State Council executive meeting on Monday that gave the green light to the projects, state news agency Xinhua said.

China National Nuclear Power received approval for three reactors, the company said in a statement on WeChat, while State Power Investment Corp said it had received approval for two units.

CGN Power Co, the listed unit of state-owned China General Nuclear Power Corp, said in a Hong Kong stock exchange filing that it received approvals for six reactors in three sites.

China currently has 56 operating reactors, accounting for around five percent of its total electricity generation, according to the World Nuclear Association.

The new reactors will be spread across Jiangsu, Guangdong, Shandong, Zhejiang and Guangxi provinces, state-run China Energy News reported.

State-controlled Chinese business news outlet Jiemian reported the total investment for all 11 reactors was expected to exceed 220 billion yuan ($30.8 billion), with construction taking around five years.

China is the world's biggest emitter of greenhouse gases, such as carbon dioxide, that are driving climate change.

A recent jump in approvals for coal-fired power plants has added to concerns that China will backtrack on its goals to peak emissions between 2026 and 2030 and become carbon-neutral by 2060.
