What is the purpose of Hillary’s trip to Angola?

Secretary of State Hillary Clinton is in Angola and she is urging the oil-producing nation to do more to fight corruption and bolster democratic institutions. About 2/3 of the people there live on less than two dollars a day. "Opportunity and prosperity for the Angolan people depend on good governance and strong democratic institutions that requires a strong civil society, transparency, accountability and vigilance in the fight against corruption." Clinton is also calling on Angola’s leaders to build on last year successful legislative elections and move ahead with plans for a presidential election. The country’s President Eduardo dos Santos has ruled for 30 years and has been criticized for postponing a presidential vote that was set for this year.
