The Republic of Djibouti, commonly known as Djibouti, is a country located on the west coast of the Gulf of Aden in northeastern Africa, with Eritrea to the north It borders Ethiopia to the west, southwest and south, borders Somalia (actually Somaliland) to the southeast, and faces Yemen across the Mande Strait in the Red Sea to the northeast. Djibouti faces the Red Sea to the east, and merchant ships enter the Mediterranean via the Suez Canal, or The Mande Strait, which is the gateway to the Persian Gulf and the Indian Ocean through the Arabian Sea, is therefore very important in its strategic location. Djibouti’s economy mainly relies on re-exported goods and leased land to earn foreign exchange. At present, Djibouti has the largest base and French base for US troops stationed abroad in Africa. The largest overseas base of the military; the Japanese Self-Defense Forces and the Chinese People’s Liberation Army have also established their own only overseas military bases (called support bases in China) in Djibouti. However, most of their domestic areas are located in the desert, with poor natural resources and weak industrial and agricultural foundations. Coupled with political instability, it is one of the least developed countries in the world. However, due to its advantageous geographical location and natural deep-water ports, the country's status as a regional trade and transshipment hub has become increasingly important.
