Mr Obama visited the country’s Ubungo power station as part of his “Power Africa” initiative, unveiled in Cape Town on June 30th, which aims to double access to electricity in sub-Saharan Africa. The Norwegian-built gas plant is the kind of public-private investment that America is seeking to encourage in Africa, where two-thirds of people have no access to power.

When we assist developing nations, we not only help improve the lives of their own citizens, but also the business environments for private-sector global investment. Our smart investments spur economic reform, advance the rule of law and improve governance to give our businesses the solid footing needed to move into Africa and grow.

The recent summit meeting in California between President Barack Obama and his Chinese counterpart, President Xi Jinping was seen by many as an important milestone in Sino-American bilateral relations. Indeed, the informality and broad range of subjects discussed between two competitive nations led many observers to draw parallels to the U.S.-Soviet summits of yesteryear.

The situation is fraught with risk for the US president. Any visit to Mandela’s bedside risks being seen as a cynical move by Obama to boost his flagging popularity, while his speeches will be analysed for signs that he is trying too hard to link his own civil rights credentials to those of South Africa’s first and most beloved black president. Meanwhile, away from Mandela’s hospital bed, Obama faces hostile criticism of US trade policies and a “NoBama” campaign organised by South Africa’s biggest trade union.

Because of African sensitivities about the presence of foreign military forces on the continent, the White House has gone to great lengths to stress that the president's trip will focus on trade and investment, democratic institution-building, and reaching out to young Africans. But in many private discussions, counterterrorism partnership will also feature prominently.

Four years after briefly stopping off in Ghana on his way home from a Group of Eight (G-8) summit, US President Barack Obama lands in Dakar on Wednesday night at the start of his first extended visit in his current designation, to the continent of his Kenyan father’s birth. But he is expected to give Kenya a miss, as its president is under indictment from the International Criminal Court.

The lack of public debate, shifting attitudes towards civil liberties, insufficient disclosure, and a decreasing terrorist threat demands that collecting Americans' phone and Internet records must meet the absolute highest bar of public consent. It's a test the Obama administration is failing.

It’s been 15 years since the people of Ireland approved the Good Friday Agreement, and President Obama called the achievement -- and the progress that followed it -- extraordinary. “For years, few conflicts in the world seemed more intractable than the one here in Northern Ireland. And when peace was achieved here, it gave the entire world hope.”
