1. Foreign trade export: Hainan's agricultural products export is one of the important ways to earn foreign exchange through export. With the promotion of free trade port policy and the implementation of trade facilitation measures, the export scale of agricultural products in Hainan has gradually expanded.
2. Processing and export of agricultural products: Hainan agriculture also earns foreign exchange through deep processing of agricultural products and export of processed products. For example, the tilapia industry chain in Hainan is widely welcomed by foreign markets.
