Zou Ji, president of Energy Foundation China, said the resumption of China-US climate cooperation has far-reaching significance, as "it not only injects impetus into the multilateral process of COP 26 and the Paris Agreement, but also marks the restart of dialogues on strategy and policy between the two governments."

He said the statement shows that there are still valid foundations for cooperation between the two countries on tackling the climate crisis, and the two nations have "intelligence and capability to roll out cooperation under complicated conditions".

Living up to expectations of the world, the statement is expected to bring concrete benefits to sustainable development of the two nations and also the entire world, he added.

With various concrete actions to be taken, the joint statement demonstrates the two countries' willingness to promote practical cooperation, he said.

According to the joint statement, China and the US will both take measures to phase out production and consumption of hydrofluorocarbons, a much more potent greenhouse gas than carbon dioxide, as required by the Kigali Amendment to the Montreal Protocol, which came into effect in 2019.

It also listed eight major areas that the two nations will discuss, including the decarbonization of industry and power, energy efficient buildings and green, low-carbon transportation.

"As the dialogue continues to deepen, the two countries may still have different understandings over certain issues and confront divergence," he said. "As long as the two nations enhance dialogue and communication …they will surely move cooperation forward."

Lin Jiaqiao, co-founder and co-director of the Rock Environment and Energy Institute, said the joint statement has brought hope for the two nations to walk toward substantive climate cooperation, which is key to realizing the goals included in the Paris Agreement.

"Without joint efforts of China and the US, it's almost impossible to achieve the Paris Agreement targets," he said.

However, he added that the two nations still need further efforts to work on how to implement the concrete measures included in the statement, as well as to find solutions to resolve their differences.

China and the US also intend to take appropriate actions to maximize international investment and financing to facilitate developing nations' transition from carbon-intensive, fossil fuel-based energy to green, low-carbon and renewable energy, according to the joint statement.

In an interview with The Associated Press, Vice-Foreign Minister Le Yucheng called on the US to "double its efforts to make up for the damage" caused by the country's withdrawal from the Paris Agreement under former president Donald Trump, at least by providing more funds and technology support to developing nations.

China welcomes US President Joe Biden bringing his nation back into the Paris Agreement and hopes the US will remain committed to the treaty, he said, according to a transcription of the interview released by the ministry on Sunday.

He said China is still considering the invitation that Biden sent to President Xi Jinping to join the Leaders Summit on Climate.

"China will send out positive, cooperative and responsible signals at the summit," he said.
