As South Korea shows, active participation in international trade does not require free trade. Indeed, had South Korea pursued free trade and not promoted infant industries, it would not have become a major trading nation. It would still be exporting raw materials (e.g., tungsten ore, fish, seaweed) or low-technology, low-price products (e.g., textiles, garments, wigs made with human hair) that used to be its main export items in the 1960s.
