South Korea Defied the Gods to Build its Steel Colossus

TL;DR

South Korea built POSCO, one of the world's most efficient steel companies, by defying Western skepticism and securing Japanese reparations funds after every Western lender refused.

Key Points

• 1.Park Chung-hee staked South Korea's industrial future on steel despite near-universal Western rejection. With per capita income of just $80, no iron reserves, and warnings from USAID and the World Bank to pursue light industry instead, Park made steel the centerpiece of his first two five-year development plans.
• 2.The KISA consortium collapsed after the World Bank declared a South Korean steel mill economically infeasible. Formed in December 1966 with US and European partners, KISA dissolved in early 1969 after the World Bank capped viable capacity at 500,000 tons and refused to loan the $130 million needed.
• 3.Park pivoted to Japan, leveraging a 1965 normalization treaty and $500 million in reparation funds. TJ Park personally lobbied MITI minister Masayoshi Ohira by invoking Japan's own strategic logic behind building Yawata Steel Works, and Japan's Big Three steelmakers signed the deal in December 1969.
• 4.POSCO was founded in April 1968 in the fishing town of Pohang, chosen for its deep-water harbor, open land, and distance from North Korea. TJ Park, a close ally of President Park Chung-hee, was installed as its leader and famously warned workers that failure with reparation funds would be 'an unforgivable sin in history.'
• 5.TJ Park's 'backwards' construction strategy let POSCO generate revenue before Phase 1 was finished. By building from rolling to iron-making rather than the conventional forward sequence, POSCO could import semi-processed slab and sell finished steel immediately, turning a profit in just its second full year, 1970.
• 6.Phase 1 was completed in July 1973 in three years — far faster than the global norm of 4–9 years. President Park then ordered capacity to grow from 1 million tons to 10 million by 1980, driving Phases 1–4 that added nearly 6 million tons and saw Korean engineers fully replace their Japanese supervisors.
• 7.The Gwangyang Steel mill, begun in 1982, made POSCO competitive against Japanese giants at 60% of average American steel costs. Its innovative single-line layout with continuous casting, basic oxygen furnaces, and computer control let POSCO sell into the Japanese market; today the company ranks eighth globally in steel production.
