The Organization for Economic Cooperation and Development (OECD) will formulate a rural development model based on South Korea's rags-to-riches growth story to help underdeveloped nations overcome poverty, Seoul's foreign ministry said Monday. As part of the OECD-Seoul government deal forged last month, Mario Pezzini, director of the OECD Development Centre, will fly to Seoul to deliver an OECD-signed copy of the agreement and hold a seminar on the project Thursday, the Ministry of Foreign Affairs said.
