Chinese President Xi Jinping on Sunday urged efforts to build a beautiful China in which humanity and nature coexist in harmony and contribute more to jointly constructing a clean and beautiful world.

Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, made the remarks in a congratulatory letter to the National Event on the Environment Day held in Shenyang, northeast China's Liaoning Province.

The ecological environment is the foundation for the survival and development of human beings, and maintaining a sound environment is the common aspiration of people of all countries, Xi said.

China has attached fundamental importance to ecological progress and has carried out fundamental, pioneering and long-term work since the 18th National Congress of the CPC, Xi said, stressing that historic, transformative and comprehensive changes have been achieved.

On a new journey of building a modern socialist country, China will maintain the strategic resolve on facilitating ecological progress, promote a comprehensive green transformation of economic and social development, and coordinate efforts on pollution control, ecological protection and climate-change response, Xi said.

Xi called for joint and solid action from the whole of society to protect the environment and leave a beautiful homeland with a blue sky, green land and clear water for future generations.
