China in the Global Response to Climate Change

China has a huge national interest in the success of the international effort to hold human-induced increases in temperature to 1.5 degrees - and therefore in global net emissions falling to net zero by 2050. China is essential to the success of the global effort - as a supplier of competitively priced equipment for the zero emissions world economy and as the world's largest current source of greenhouse gas emissions. Success is more likely for China and the world with international specialization in goods production for the zero emissions economy. This will require open international trade, with China supplying equipment and drawing zero emissions semi-processed goods from abroad. Success is more likely and will be achieved at a lower cost if there is close cooperation across national boundaries.
