Due to the presidential election in the US this year, there is a possibility of further changes or even reversals in US climate and energy policies, Gu said, adding that it is necessary for China to pay attention to this and adjust strategies promptly while steadfastly adhering to established goals and pathways.

However, cooperative efforts to address climate change have become a cohesive factor in the relationship between China and the US, he said.
