This is only the tip of the iceberg for China on environmental issues. The people there are fed up and I think the government is going to be forced to enact some actual environmental protection. Eventually we won't be able to export our pollution to there anymore and will have to find some other country to setup dirty industry in.
Eventually we might run out of countries with exploitative and abusive governments and have to actually factor in the environmental costs of our products, but probably not in my lifetime. We still have most of Africa to exploit, not to mention South and Central America and the Middle East.
