The environmental externality must be internalized strongly and consistently throughout the "developed" and developing economies [1]. Participation from the two groups is a necessary condition for addressing the air pollution issue.

Meanwhile, the situation in London is similar in South Korea [2]. Most likely, worse: South Korean government is afraid of further regulating the domestic industry, when it should. Over the past decade or so, Chinese government has moved a lot of their factories to the East coast which faces SK in the West. Both SK and Chinese citizens must acknowledge this is a mutually-interested issue and take concrete steps to collaborate while minimizing finger pointing. I am convinced this is a tractable scientific and social/diplomatic problem. One proposal is to set up a joint government-backed venture/think tank that incrementally tackles this issue at a tech/policy level. Such a small step but no where near it...
