** ADVANCE FOR MONDAY, SEPT. 3** A Chinese foreman walks past laborers working on the construction of military officer housing, donated by China, in Bissau, Guinea-Bissau, Jan. 3, 2007. Market stalls are just one of the most visible signs of China's massive penetration into African economies. The Asian giant _ a ready buyer of oil and other raw materials for more than a decade _ is also a major bidder on construction projects, a multi-million-dollar lender and a growing player in Africa's telecommunications and textile industries.
