Which industries did South Korea develop first under its economic plans?

Under the series of economic development plans initiated in 1962, South Korea initially prioritized the development of textiles and light manufacturing industries.1

Following this initial phase, the government shifted its focus in the 1970s toward heavy industries, such as iron, steel, and chemicals, before eventually transitioning to high-technology sectors like automobiles, electronics, and information technology. This rapid transformation, often referred to as the "miracle on the Han River," was driven by export-oriented strategies and strong government support for large, family-controlled conglomerates known as chaebols.12
