LUANDA, ANGOLA MARCH 31: A Chinese businesswoman talks on her mobile phone outside a shop on March 31, 2007 at the Chinese market in Luanda. Luanda is full of newly arrived Chinese who do business in many different fields. Tens of thousands of Chinese has come to Africa the last years to work in infrastructure projects and businesses. Chinese companies are often the lowest bidders for contracts, pricing out the more expensive European companies. The Chinese people often live where they work and rarely interact with the local population. Most Chinese don't speak English and they are mostly staying in the compounds cooking their Chinese food.
