Counterplan spills over to solve broader disputes – that checks multiple extinction risks

Three Dimensions of Cooperation China-U.S. cooperation is multi-dimensional. It covers three areas: global challenges; bilateral trade, economic, cultural and educational cooperation; and military exchanges and security cooperation. The common challenges facing mankind have never been so daunting as they are today -- climate change, nuclear weapons proliferation, terrorism, pandemics, natural disasters, drug trafficking, just to name a few. No country, no matter how powerful it is, is able to meet these challenges alone. Common challenges bring people together. Mankind is bound to unite for its survival. When China and the U.S., the world's two largest economies, cooperate, it makes a difference. In November 2014, President Xi Jinping and President Obama made a joint pledge on reducing pollution and carbon gas emissions. As a result, the upcoming United Nations conference on climate change to be held in Paris from Nov. 30th to Dec. 11th this year, looks much more promising. Nuclear weapons proliferation also poses a serious threat to international peace and security. Of all the global challenges it is the most complicated. The North Korean nuclear issue is the other major concern along with Iran. The Six-Party Talks on this issue have so far stalled for six years and at present show no sign of resuming any time soon. Even so, the fact that China and the U.S. have agreed to pursue the goal of denuclearization on the Korean Peninsula has kept the issue from getting out of control. The year 1950 witnessed violent confrontation between China and U.S. in the Korean theater, but 2015 is a long way from 1950. China-U.S. cooperation has been a significant factor in keeping the lid on this conflict. Such cooperation, whether on Iran, North Korea or climate change, is an important building block for the new model of the major countries relationship. The way to conceive of this relationship is as a big house. It has to be built gradually, block by block. The more building blocks laid, the faster that house will be built. As President Xi Jinping has put it: "A sound China-U.S. cooperation can become a ballast stone of world stability and a booster of world peace. "
