GUIYANG - China will commit to its international obligations and work with countries around the world to make a better Earth, President Xi Jinping said in a congratulatory letter to an environmental forum on Saturday.

In the letter, Xi extended his congratulations on the opening of the Eco Forum Global Annual Conference 2013, which was held in Guiyang, capital city of Southwest China's Guizhou province.

The forum concentrates on the international community's common concerns about building an eco-civilization, Xi said.

The president said building a beautiful China is an important part of the Chinese dream of national rejuvenation.

China will work in line with the idea of respecting, complying with and protecting nature, and implement the national policy of saving resources and protecting the environment, so as to promote green, recycling and low-carbon development, he said.

To leave a good environment for future generations, China will incorporate ecological progress into its economic, political, cultural and social development, and shape the industrial structure, production mode and people's lifestyles in the spirit of saving resources and protecting the environment, Xi said.

Vice Premier Zhang Gaoli attended the forum.

Building an eco-civilization is of great significance to China's construction of a moderately prosperous society in all respects and the Chinese dream of realizing national revival, Zhang said in his speech at the ceremony.

"It is also conducive to the sustainable development of the world," Zhang said.

He called on all parties to make joint efforts to enhance international exchanges and cooperation, so as to make positive contributions to building a good environment on Earth.
