China and the United States were at an impasse on Monday at the United Nations climate change conference here over how compliance with any treaty could be monitored and verified.
China, which last month for the first time publicly announced a target for reducing the rate of growth of its greenhouse gas emissions, is refusing to accept any kind of international monitoring of its emissions levels, according to negotiators and observers here. The United States is insisting that without stringent verification of China’s actions, it cannot support any deal.
Translation: any "deal" at Copenhagen is DOA at this point.
And do note: "Earlier Monday, a group of poor nations staged a brief walkout from the bargaining table, and a chaotic registration system left thousands of attendees freezing outside the conference hall..."
