Chinese President Xi Jinping has sent a congratulatory letter to the Eco Forum Global Annual Conference Guiyang 2018, which opened in the capital of southwest China's Guizhou Province Saturday.

"Ecological conservation concerns the future of the humankind, and it's the common goal of all nations to build a green home," Xi said in the letter.

"The international community should strengthen cooperation and work together to build an ecological system that respects nature and features green development, to pursue global sustainable development," he said.

Xi said he believed that the annual conference, themed "embracing a new era of eco-civilization: green development with high priority to ecology," would help all parties strengthen consensus and cooperation for the development of global ecological civilization.

"China highly values ecological and environmental protection," the president said. "Guided by the conviction that lucid waters and lush mountains are invaluable assets, the country advocates harmonious coexistence between humans and nature, and sticks to the path of green and sustainable development."

"China is ready to work with the international community to realize the 2030 Agenda for Sustainable Development and build a clean, beautiful world."
