At the beginning of this year,the BRICS countries welcomed a wave of new members.On New Year’s Day,Saudi Arabia,Egypt,the United Arab Emirates,Iran and Ethiopia became full members,doubling the number of BRICS members from five to ten.At present,BRICS,as a multilateral cooperation organization of developing countries,is on the road towards substantial expansion and rapid development.In both historical and practical terms,the expansion of BRICS membership has profound historical logic and contemporary implications,which will have a significant impact on the world’s pattern and international order.
