There is tremendous pent up frustration with the increasing corrupt and irrelevant government in China. Cracking high tariffs on goods from China likely will put 1000 times more pressure than all of the finger wagging and human rights pep talks the west has made in that last few decades, increasing unrest and civil collapse in China. However the west really likes to look the other way to get low wage / low cost / pro-business manufacturing, so likely tariffs will be lobbied against by US's own global business titans.
Perhaps an NGO / consumer information institution to lead a product labeling campaign so at least consumers of the world can see 'virtual carbon' production cost on product packaging. Then consumers and businesses can more directly make choices about how carbon neutral their supply chain is. Currently there is very little information available on this when purchasing decisions are made in the west.
