China gave priority to free aid in the early days, and then it gradually turned into paid aid. Among them, North Korea, Vietnam, Laos, Cambodia, Indonesia, Nepal, Albania, Cuba, Libya, Sudan and other countries are mainly given free assistance, in order to hope that they will embark on the socialist road, and the goods include food, weapons, industrial products and so on.
Later, the aid to Myanmar, Pakistan, Bangladesh, Sri Lanka, Lebanon, Egypt, Tanzania, Zambia, Mozambique and other countries was based on national interests and international influence, with low-cost aid and interest-free loans as the main aid, assisting army equipment, engineering aid, missiles, ships and planes.
