China doesn't have much oil. There dependency on oil is a huge weakness, and they are easily blockaded as well, making the problem of importing oil in wartime problematic as well. Their move away from oil is more national security even if it does help the environment.

How are they "easily blockaded"? I thought their shipbuilding capacity exceeds that of the US, and their navy is now larger.
