But, beyond its borders, the country has been the world's biggest investor in coal power.
"Chinese banks' and companies' investments in coal abroad are a cause of major concern because of their potential to lock in more climate warming emissions in our carbon-constrained world," said Huang Wei, a climate and energy campaigner at Greenpeace East Asia.
Chinese financial institutions are the world's largest investor of overseas coal plants, pumping in $15 billion in coal projects from 2013 to 2016 through international development funds, according to the Natural Resources Defense Council, a U.S.-based non-profit environmental advocacy group. There's another $13 billion in proposed funding.
That is even as data from the International Energy Agency show a slowdown in coal power investment globally.
