The LA Times has an excellent two-part series on the politics of petroleum in the Third World. The first series focused on Kazakhstan, and the second Angola. Both are excellent reads packed with information on how corrupt these governments are.
Here are the links:
Angola: Gusher to a Few, Trickle to the Rest
Just past the misnamed Beautiful Rose Farm, a shantytown without running water or sewers, is a lush, gated compound with spacious houses, manicured gardens and tennis courts that ExxonMobil built for its employees.
Besides the foreigners, the development also has benefited a few well-connected Angolans: A local businessman close to President Jose Eduardo dos Santos was hired by the oil company to construct the complex, and a former army chief of staff collects rent on the land, according to an oil industry consultant's report and a source familiar with the arrangement.
Kazakhstan: Oil Adds Sheen to Kazakh Regime
Some of Washington's top political consultants traveled to this city in the summer of 1998 to huddle with Kazakh President Nursultan Nazarbayev. Their daunting mission: Convince the world that his oil-rich, authoritarian regime was actually a budding democracy.
This political SWAT team launched the opening salvo in a high-powered, high-priced lobbying campaign that seized on America's need for oil to win U.S. support for a government with a penchant for shuttering newspapers and manipulating elections.
