Benign interactions between China and the U.S. in climate governance are highly anticipated as humanity is faced with mounting global climate change challenges and climate governance has entered a crucial stage.

Climate change concerns the welfare of people around the world and mankind’s future. Various parties need to jointly address the issue with ambition and determination.

President Xi Jinping's pledge on Saturday of China's further commitments to tackling global climate challenges consolidates his earlier announcements for the country to peak emissions before 2030 and achieve carbon neutrality before 2060.

It is crucial to note that the gains to China and the world from climate action are far greater in the immediate years than in the later years, when the socioeconomic cost of mitigation would have risen exponentially.
