As an investor in renewables, China is well in the lead of ever other nation.
Either the Pew report or that article is giving you an incomplete picture.
China, despite being a leader in nuclear and renewable power, is also going balls out to build coal-gasification plants.
China will be closing some coal power plants, but only ones nearest to its major cities (and responsible for the atrocious air quality). These will be replaced with 50 coal-to-gas plants in NW China and the synthetic natural gas will be shipped to new power plants in/near the cities. Cleaner air, but more CO2 per unit of power.
As a side note, China is responsible for about half the world's coal consumption, with no declines predicted.
