South Korea will focus on boosting its agricultural exports to Southeast Asian countries that already make up the world's second-largest market for South Korean goods, a state-run trade organization said Wednesday, a bid to weather a slowing demand in other regions. The growth of the country's food exports is slowing due to a global economic downturn and weakening of the Japanese currency, which have led to a particularly significant cut in shipments to Japan, the world's single largest importer of South Korean foodstuff, according to the Korea Agro-Fisheries & Food Trade Corp., better known as AT.
