While forging ahead with domestic green transition, China will proactively participate in global environmental governance with intensified international cooperation, Minister of Ecology and Environment Huang Runqiu said at a national event held in Shenyang, capital of Liaoning province on Sunday.

Upholding Xi Jinping Thought on Ecological Civilization, China has made significant environmental improvement, he said while addressing the opening ceremony of the event themed "Building together a clean and beautiful world" on the World Environment Day.

In 2021, the period of heavy air pollution in major Chinese cities, for example, went down by 53.6 percent from the 2015 level, he noted.

During the 14th Five-Year Plan (2021-25) period, China has entered a critical moment when environmental protection is progressing from quantitative to qualitative changes, Huang said.

China will endeavor to promote the comprehensive green transition of economic and social development, as it strives to synergize pollution control and carbon reductions in this period, he said.

"Faced with the ecological and environmental challenges, all people are members of a community where they rise and fall together," the minister emphasized.

He pledged to beef up cooperation with the international community to cope with the global crises of climate change, marine pollution and biodiversity loss.

To help realize goals in the United Nations' 2030 Agenda for Sustainable Development, China will consistently promote the construction of a green Belt and Road and also deepen South-South cooperation, he said.
