Cooperation on this important issue will pave the way for joint efforts to overcome other global challenges. The wholehearted cooperation of China and the United States is essential for the success of any effort to solve global challenges. It is time for concerted action, not squabbling.

China and the United States should proceed from easier topics to more difficult ones, seeking new paradigms of interaction under new circumstances. Success in climate cooperation, if achieved, may serve as a demonstration of feasibility for other areas.

Areas with a high concentration of energy-intensive industry — in particular those that are fast-growing and emission heavy — will be hardest hit. In response, the central government should step up its efforts to help these areas embrace carbon neutrality through such means as carbon quota trading.

A Cornell University program centered on community-building and education is a case-study in U.S.-China cooperation.

U.S. President Joe Biden is making a run at renewing America’s global leadership on climate governance. The World Earth Day summit provided an inflection point that attracted attention from around the world.

Four years ago, Donald Trump rashly withdrew the United States from the Paris Agreement. Under President Joe Biden it has returned, but it needs to do more. Kerry’s visit with his Chinese counterpart was a good start.

The Biden administration is attempting to merge some domestic priorities with foreign relations, which should create some room for cooperation. The pandemic, economic recovery and climate change are good places to start.

As China-U.S. relations deteriorate, communication and cooperation on energy and environmental issues have ground to a halt. Yet climate cooperation between the two largest polluters during the Paris climate conference in 2015 provides some lessons to be learned.

As the United States prepares for a radical course-correction on climate change, China is raising its game. Climate action has become yet another front in the competition between the world’s two largest economies. Who will cross the net-zero-emissions finish line first?

China’s pledge in September to pursue carbon neutrality by 2060 was followed by a similar pledge from Japan a month later. With these commitments being made at a time when the US has withdrawn from the Paris climate accord, it is easy to interpret them as part of the ongoing geopolitical competition for global leadership. But managing climate change is not a zero-sum game. Here, national competition to strengthen ambitions and policies benefits everyone.
