A communication mechanism will be established to promote subnational climate cooperation between China and the United States, China's top economic planner said on Tuesday.

The mechanism will encourage provinces, states, cities and enterprises of the two countries to strengthen policy exchanges, share best practices and expand practical cooperation on climate change and green and low-carbon issues, China's National Development and Reform Commission spokesperson, Li Chao, told the media at a press conference on Tuesday.

Climate leaders from the two countries convened in Berkeley, California, on May 29 to discuss climate action and progress at the U.S.-China High-Level Event on Subnational Climate Action.

The meeting marked an important step by the two countries to implement the consensus reached between the two heads of state at the San Francisco summit and the Sunnylands Statement on Enhancing Cooperation to Address the Climate Crisis.

Li said around 300 representatives from governments, enterprises, universities, think tanks and nongovernmental organizations discussed issues, including green infrastructure, clean energy and low-carbon technology, resulting in several practical outcomes.

"The vision of China-U.S. climate cooperation is being translated into real action at the subnational level," Li said, adding that the two sides have agreed to hold the meeting on a regular basis, with the second one scheduled to take place in China next year.
