The five BRICS countries should strengthen unity and cooperation to uphold multilateralism and promote the development of the international order in a more just and rational direction, a senior Chinese official has said.

Speaking at the 9th Meeting of the BRICS High Representatives for Security Issues held here from Thursday to Friday, Yang Jiechi, a member of the Political Bureau of the Central Committee of the Communist Party of China (CPC), said that as the world is undergoing profound changes unseen in a century, BRICS countries (Brazil, Russia, India, China and South Africa) should strengthen unity and cooperation to deal with such changes.

The BRICS should fully implement the consensuses reached by leaders of the five countries in previous BRICS leaders' meetings and consolidate cooperation in political security, economy, trade and finance, and people-to-people exchanges, said Yang, who is also director of the Office of the Foreign Affairs Commission of the CPC Central Committee.

BRICS countries should support each other, strengthen the ability to withstand risks and cope with complex situations, and jointly oppose external intervention, Yang said.

Brazil, Russia, India, China and South Africa should adhere to the concept of open and inclusive cooperation, promote the "BRICS Plus" cooperation model, and create an open and diverse network of partnerships, he said.

Yang added that the BRICS should uphold multilateralism, defend the purposes and principles of the United Nations Charter, and promote the development of international order in a more just and rational direction.

For his part, Brazilian President Jair Bolsonaro, during his meetings with the delegation leaders from the BRICS, conveyed his cordial greetings to the leaders of BRICS countries and said he is looking forward to the leaders' meeting which will be held soon in Brasilia.

Bolsonaro said that the participating representatives in the two-day meeting had high-quality discussions, which showed the high-level cooperation among BRICS countries.

He said he will soon visit some Asian countries including China, and is looking forward to pushing for new developments in bilateral relations through the visit.

During the two-day meeting, participants exchanged in-depth views on counter-terrorism, cybersecurity, and regional and international hotspot issues, and reached broad consensus.

All participants agreed to strengthen unity and cooperation, help work towards fruitful results of the upcoming BRICS leaders' meeting in November, jointly defend multilateralism, and make greater contributions to safeguarding world peace and promoting common development.

During the two-day meeting, Yang also held bilateral talks with delegation leaders from other BRICS countries.
