What you want to do is set up a charity in a Third World country and give them a steady stream of money that goes to the governmental leaders for their own personal projects, like a school or something. Do this for a few years and then you're positioned to get control of the country's natural resources at well-below market prices due to, ah, corrupt local leaders willing to sell out their country's interests in exchange for more 'charity'.
