Autonomous import/export refers to the ability of a country to engage in international trade without significant interference or control from other countries or international organizations. This means that the country has the freedom to make its own decisions regarding the import and export of goods and services, without being heavily influenced by external factors. Autonomous import/export allows a country to pursue its own trade policies and strategies based on its own economic interests and priorities. **

Export-import trade refers to the exchange of goods and services between countries. It involves the sale of goods and services from one country to another (export) and the purchase of goods and services from another country (import). This trade is essential for the global economy as it allows countries to access products and resources that they may not have domestically, while also providing opportunities for businesses to expand their markets and reach new customers. The balance of export and import trade is an important indicator of a country's economic health and its relationship with other nations. **

Germany imports and exports potatoes to meet the demands of its domestic market and to take advantage of different varieties and qualities available in other countries. By importing potatoes, Germany can ensure a stable supply throughout the year and access specific types of potatoes that may not be grown domestically. On the other hand, exporting potatoes allows Germany to showcase its high-quality produce to international markets and generate revenue from its agricultural sector. **

Germany exports and imports grain to meet the demands of its domestic market. While Germany is a major producer of grains such as wheat and barley, it may not always produce enough to satisfy its own needs. By importing grain, Germany can ensure a stable food supply for its population and support its food processing industry. At the same time, exporting grain allows Germany to take advantage of international markets and generate revenue from its surplus production. **

Cuba's main imports include food, petroleum, machinery, and chemicals. The country's primary exports are sugar, tobacco, nickel, medical products, and citrus fruits.
