Chinese Vice Premier Han Zheng on Thursday said China-U.S. cooperation on climate must be based on the foundations of the Paris Agreement in talks via video with John Kerry, visiting U.S. special presidential envoy for climate.

Addressing climate change is an important part of China-U.S. cooperation, which must be based on trust, Han said. 

Noting China's goal of having CO2 emissions peak before 2030 and achieving carbon neutrality before 2060, he said China has always delivered on its words in addressing climate change.

The goal demonstrates China's firm commitment to implementing the Paris Agreement, its commitment to intensify action on climate change and its commitment to building a community with a shared future for mankind, Han said.

He called on the U.S. to make joint contributions to the global fight against climate change, focusing on the implementation of the joint statement addressing the climate crisis and under the objectives and principles of the United Nations Framework Convention on Climate Change and the Paris Agreement.

For his part, Kerry said that the United States and China should maintain constructive engagement and jointly address global challenges.

Noting that China has made tremendous efforts in addressing climate change, he said the U.S. is willing to strengthen contact and communication with China, step up implementation of the Paris Agreement and jointly address the threat of global climate change.
