With an area of approximately 30.2 million square kilometers, Africa is the third largest continent on the planet. This large territory, inhabited by more than a billion people, presents great physical, ethnic, cultural and economic diversity.

Underground wealth drives mining. South Africa has large reserves of diamond, chromium, platinum, gold (the world's largest producer), among other ores. Another highlight is the large production of oil and natural gas in sub-Saharan African countries. Tourism, promoted in several natural parks, is another important source of financial resources.

The Southeast Asian economy is basically focused on the primary sector: agriculture and mineral extraction.

Another crop of great relevance to the Southeast Asian economy is rubber, especially in Malaysia, given that this is the largest producer of latex of plant origin in the world. The subcontinent is also a major producer of tea, sugar cane and black pepper, including the production of tin (Malaysia) and wood and oil (Indonesia). Indonesia, incidentally, is one of the members of OPEC (Organization of oil exporting countries), which brings together the largest oil producers in the world.
