What is the specific difference between buying a loan and selling a loan, and what are the requirements for both parties? What is the concept of excellent purchase and excellent loan, and how to choose it in operation? The difference between buying and selling loans is mainly the difference between borrowers. For China's export trade, the borrower of buyer's credit is a foreign importer or importer's bank, and the borrower of seller's credit is a domestic exporter.

Preferential export buyer's credit (preferential purchase) refers to a specific loan provided by The Export-Import Bank of China or China Development Bank in the form of export buyer's credit to promote economic and trade cooperation with key countries and regions.

Concessional loans (excellent loans) refer to medium and long-term low-interest loans provided by The Export-Import Bank of China to the governments of developing countries.
