In this Washington Post opinion piece, Tony Blair, former prime minister of Britain and founder of the Africa Governance Initiative, highlights South Korea’s transformation from aid recipient to aid donor over the past 50 years and writes that, as national and development leaders prepare to meet in the country this week for the Fourth High Level Forum on Aid Effectiveness, “The international goal must be to make sure many more countries are transformed.” Noting that development assistance has helped improve markers in areas such as health and education, Blair writes that transforming countries “will require building on the success of aid, broadening our thinking beyond aid to strengthen states and markets, and developing a new set of global relationships to tackle global issues” (11/25).
