Xi expressed appreciation for Ulan Bator's plan to plant 1 billion trees by 2030, saying that Beijing stands ready to explore the joint establishment of a center to cooperate on tackling desertification.

The two sides should also strengthen exchanges and cooperation between legislative bodies, governments, political parties, and at local levels and in sectors including science and technology, education, health, tourism, media, youth and people-to-people exchanges, he said.

In doing so, the president said, the two sides can cement the foundation for bilateral relations and bring more benefits to their peoples.

He stressed that the nations shared common interests in international and regional affairs, adding that China stands ready to closely coordinate and cooperate with Mongolia to jointly uphold true multilateralism, resist bloc confrontation and safeguard unity and cooperation of the international community.

Mongolia is willing to conduct closer political exchanges with China, extend its staunch support and deepen their ironclad friendship, he said.

He reiterated his nation's firm adherence to the one-China policy, which he said will never change.

The Mongolian side speaks highly of China's active contribution to upholding global peace, stability and development and the international system with the United Nations at its core, he added.

The two heads of state witnessed the signing of cooperative agreements in areas including economy, trade, investment, customs, and tackling desertification.
