BEIJING — Xi Jinping on Wednesday called on all countries to work together for a clean and beautiful world and tackle climate change through cooperation.

Delivering a report to the opening of the 19th National Congress of the Communist Party of China, Xi said, "To make new and greater contributions for mankind is our Party's abiding mission."

Xi called on the people of all countries to work together to build a community with a shared future for mankind, to build an open, inclusive, clean, and beautiful world that enjoys lasting peace, universal security, and common prosperity.

"No country can alone address the many challenges facing mankind; no country can afford to retreat into self-isolation," Xi said.

The challenges he mentioned include global economic growth that lacks energy, the widening gap between the rich and the poor, hotspot issues in some regions, as well as unconventional security threats such as terrorism, cyber-insecurity, major infectious diseases, and climate change.

For climate change in particular, Xi proposes that all countries in the world be good friends to the environment, cooperate to tackle climate change, and protect the planet for the sake of human survival.

The report describes China as having been taking "a driving seat in international cooperation to respond to climate change" and "an important participant, contributor, and torchbearer in the global endeavor for ecological civilization" over the past five years.
