South Africa is one of the five largest mineral countries in the world, with good infrastructure, abundant resources and highly open economy. Mining, manufacturing and agriculture are the three pillars of economy, and deep mining technology is in a leading position in the world. The development level and regional distribution of various sectors of the national economy are unbalanced, and the income distribution is uneven. South Africa is famous for its rich mineral resources, with more than 60 kinds.

The export of mineral products accounts for about 50% of export income, and about 12% of the labor force in China is engaged in mining. The manufacturing industry has complete categories and advanced technology.

South Africa's De Beers Company is the largest diamond production and sales company in the world, with total assets of $20 billion. Its turnover once accounted for 90% of the world diamond supply market, and it still controls 60% of the world rough diamond trade.

In normal years, food can be exported except for self-sufficiency. The arable land accounts for about 13% of the national territory, but the fertile land only accounts for 22% of the arable land. The main crop is corn. The quality of canned food, cigarettes, wine, coffee and drinks meets international standards, and wine enjoys a high reputation in the world.
