Don't expect a lot of cooperation from China
China is not about to stop building coal plants at one a week nor put stringent air quality controls on them. They signed onto Kyoto because they had no obligations under the treaty. They have no problem taking the tar sands bitumen from Canada that the US won't via the rejected Keystone XL pipeline. They are actively buying up whatever resources they can around the world such as oil from Iran that other countries are boycotting.
China has over 1 billion people they need to get into the 21th century. Unfortunately, that won't happen if they are concerned with niceties such as pollution. Until the Chinese people protest in huge numbers, not much is going to change there.
