China's chief negotiator for climate change talks expressed optimism about the UN climate talks in Cancun, stating that positive results are possible as long as all parties show sincere political will. Despite clashes between rich and developing nations over the future of the Kyoto Protocol, China believes that the talks will ultimately yield meaningful outcomes in line with the Bali road map. Su Wei emphasized the importance of compromising on minor issues while maintaining principles, such as the debate over the continuation of the Kyoto Protocol. China accused certain developed nations of attempting to sabotage the Kyoto Protocol, the United Nations' primary tool in the fight against climate change, in a tense standoff with Japan, Russia, and Canada. Despite pressure, China, the world's largest carbon emitter, remains steadfast in its commitment to the Protocol. With the first phase of Kyoto set to expire in 2012, the uncertainty of what comes next is concerning for investors seeking clarity on climate policies and funding. While most wealthy nations have agreed to binding emissions targets under Kyoto, the United States has notably not joined, and developing nations like China are only required to take voluntary steps to reduce emissions. The United States and other wealthy countries are pushing for a new international agreement that would eliminate the traditional divide between developed and developing nations in addressing greenhouse gas emissions. Developing countries like China and India, however, are hesitant to commit to specific targets without first seeing significant reductions from industrialized nations.
