The so-called "emerging economy" refers to a country or region's booming economy and becoming an emerging economic entity, but there is no accurate definition. The British economist divided emerging economies into two echelons. One is a BRICS country, and the other is an emerging diamond country.

Although the economic growth rate of emerging economies has slowed down, experts have analyzed that after experiencing the impact of the financial crisis, emerging economies have adjusted their economic structures, increased their foreign exchange reserves, improved their financial systems, and enhanced their ability to resist risks, and the world economy will continue to grow.

At the same time, South-South cooperation has also reduced the dependence of emerging economies on the economies of developed countries. The formation of South China market and the cooperation between China and ASEAN also ensure the sustained growth of the world economy.
