A difficult question from one of China's representatives to the WTO:
"The United States per capita emission rate is four times as big as China's. Does that mean we can impose 400 percent tax rates on all imported American goods? If so, the result is a global trade war that is good for no one and no use at all in the fight against climate change."
And this, too:
"Frankly, if tariffs are being implemented unilaterally, they cannot be objective and cannot be non-discriminatory."
