You say that like it’s a bad thing.
Is the coal China is buying in all their new start up coal power generating plants anthracite or ignite? Are most of the World’s coal reserves (proven or known) hard or soft?
Most of the remaining “good” coal in the world is bituminous. The BTU content of lignite is much less than bituminous and it gives off a lot of crap when burned. I don’t know what China burns. Try a wiki search.
