RIO DE JANEIRO -- China stands ready to deepen coordination and cooperation with the United Nations to jointly advocate for a more just and equitable international order, Chinese Premier Li Qiang said here on Tuesday.

Li made the remarks in his meeting with UN Secretary-General Antonio Guterres on the sidelines of the 17th BRICS Summit.

Over the 80 years since its founding, the United Nations has made vital contributions to safeguarding world peace and tranquility while promoting common development, Li said.

Cautioning that the world is facing mounting unstable and uncertain factors, Li said that the UN needs to play a better role.

The vision of building a community with a shared future for mankind and the three major global initiatives, proposed by Chinese President Xi Jinping, are highly consistent with the purposes and principles of the UN Charter, as they embody China's steadfast commitment and pragmatic approach to support multilateralism and the work of the UN, stressed Li.

The more complex the international situation becomes, the more necessary it is to uphold the authority of the UN, said Li, stating that China firmly supports the UN's central role in global governance and stands ready to work with all parties to practice true multilateralism and to better advance the UN's work.

As the global security faces grave challenges, China has made extensive efforts to promote dialogue for the political settlement of hotspot issues, and will continue to support the UN in playing its unique role in de-escalating tensions, he said.

The premier noted that all parties should prioritize development on the international agenda, work together to enhance global development cooperation, allocate resources first and foremost to key areas such as poverty alleviation, education, employment and capacity building, and revitalize the global development partnership.

China, as a responsible major developing country, will continue to firmly pursue opening-up, share its opportunities with the world and promote common development, said Li.

China supports the United Nations as the main channel in addressing the gaps in global governance in emerging areas such as artificial intelligence, cyberspace, the polar regions and outer space, he added.

For his part, Guterres expressed appreciation for China's long-term commitment to multilateralism, as well as its firm support for the work of the United Nations.

The UN chief noted that the three major global initiatives proposed by President Xi dovetail with the goals of the United Nations.

The Chinese side, he said, has made important contributions to promoting the political settlement of hotspot issues, reforming the international economic and financial system, and safeguarding the interests of developing countries.

In the face of the current international situation, the United Nations looks forward to taking its 80th founding anniversary as an opportunity to strengthen cooperation with China, safeguard the authority of the UN Charter and international law, support multilateralism, oppose unilateralism, jointly address climate change and other global challenges, enhance global governance of artificial intelligence, and promote world peace and development, he added.
