Kolwezi, an important city in the Katanga Province of the Democratic Republic of Congo (DRC), is located in the southeastern part of the country in the heart of the Copperbelt, adjacent to the Zambian border, and is one of Africa's renowned mining centers. As a key node in the global copper and cobalt mining industry, the surrounding area is rich in high-grade copper and cobalt deposits, attracting a number of international mining companies, and the economy is highly dependent on the mining and processing of minerals, known as "Copper City". The city is about 1,500 meters above sea level and has a cool climate, with an average annual temperature of about 20 degrees Celsius, characterized by a tropical grassland climate. With a population of about 500,000, the city is a multi-ethnic settlement with French and Kiba as the main languages and a strong mining culture, but the infrastructure is still under development. Kolwezi is not only the economic pillar city of the Democratic Republic of the Congo, but also an important hub connecting the resource corridors of southern Africa, which is strategically important to the global supply chain.
São Tomé and Príncipe is an island country in west-central Africa, consisting of the islands of São Tomé and Príncipe and the surrounding islets, with the capital, São Tomé, located in the northeastern part of São Tomé. Located on the Gulf of Guinea, about 200 kilometers from the African continent, the country was colonized by Portugal in the 15th century and became independent in 1975, with Portuguese as the official language and an economy based on agriculture (cocoa, palm oil) and tourism. It should be noted that "Java" is not a city or region of the country; Java is the main island of Indonesia, with cities such as Jakarta and Surabaya, and has nothing to do with São Tomé and Príncipe, possibly due to a confusion of names.
