South Korean President Park Geun-hye was to hold a summit with Swiss President Didier Burkhalter on Monday as she seeks to forge greater cooperation with the world's most competitive economy, especially in the vocational training and high-tech industries. Switzerland, though small in size with a population of mere 8 million, is the world's 20th-largest economy in terms of gross national product. The World Economic Forum (WEF) found the European economy the most competitive in the world for the fifth consecutive year last year.
