There is a new dimension to the alliance, however, and to the relationship with China. This year, China surpassed the US as the world’s largest emitter of greenhouse gases. China argues, correctly, that it is still behind the US and Japan in per capita emissions, but this does not reduce the costs imposed on the world (including Japan and the US).
不过这一同盟以及与中国的关系现在又出现了一个新问题。今年中国超越美国成为世界上最大的温室气体排放国。尽管中国不无道理地争辩说它的人均排放量依然比美国和日本低，但是这并没有减少给整个世界（包括美国和日本）所造成的代价。通过合作帮助中国更清洁地燃烧它的煤符合所有三个国家的利益。
