This blog is part of a blog series on past large-scale international investment programs and the lessons they provide for the investment push needed for development and climate action today. You can read the introduction to the blog series <\/em>here<\/em><\/a> and part 1 <\/em>here<\/em><\/a>.<\/em><\/p>\n

In the decades after World War II, South Korea received one of the largest influxes of foreign funds that any country has ever received. From 1946-1978, US economic aid to South Korea amounted<\/a> to $6 billion, just barely less than the $6.89 billion the US provided to all <\/em>of Africa in that period. South Korea also received<\/a> another $6.6 billion in US military aid from 1946 to 1978. At the peak of the economic aid, it amounted to 21 percent of South Korea\u2019s gross domestic product (GDP<\/a>) and 70 percent of its domestic revenue<\/a>.<\/p>\n

That period also launched one of the most remarkable surges in economic and human development in history. Poorer than Haiti<\/a> in 1950, South Korea\u2019s GDP per capita is now 17 times higher<\/a> than Haiti\u2019s. In 1950, nearly one in five Korean children died<\/a> before the age of five. By 1975, that number<\/a> was about one in thirty. South Korea is now a significant aid donor<\/a> and in 2024 it imported<\/a> over $100 billion in goods and services from the United States.<\/p>\n

South Korea\u2019s domestic policy was also fundamental to this transformation. American aid to South Korea came in the context<\/a> of a developmental state that turned towards export-oriented industrialization. The South Korean government protected strategic industries with tariffs and provided them with extensive subsidies that companies needed to earn through effective performance. The government also nationalized banks and closely controlled foreign exchange.<\/p>\n

While South Korea\u2019s success was about much more than just US assistance, it is an extraordinary example of how external finance and state-coordinated developmentalism can combine for rapid developmental progress. American finance was utilized in alignment with South Korea\u2019s development strategy, with the South Korean government frequently ignoring American policy advice but continuing to receive American support due to its strategic importance in the Cold War. In contrast to fears that large-scale external finance necessarily disrupts political incentives and macroeconomic stability, the huge inflows of American finance allowed South Korea to make transformative investments while preserving fiscal and financial stability\u2014and the result was a country that went from an impoverished agrarian economy to a dynamic industrial power in just a few decades.<\/p>\n

The Rhee era<\/strong><\/h5>\n

The Korean Peninsula formally split into the Republic of Korea (South Korea) and the Democratic People\u2019s Republic of Korea (North Korea) in 1948, and Syngman Rhee became South Korea\u2019s first president. North Korea\u2019s invasion of South Korea in 1950 sparked the Korean War, which lasted until 1953. The US sent troops to support South Korea and it provided extensive aid to South Korea after the war, peaking<\/a> with $387 million in economic aid in 1957, 21 percent of South Korea\u2019s GDP<\/a>. This aid consisted almost entirely of grants<\/a>. Much of it was for consumption<\/a>, with war-devasted Korea needing extensive support.<\/p>\n

American officials frequently expressed frustration with the dynamics of this aid, but Rhee managed to keep it flowing in line with his priorities. Rhee insisted<\/a> on large-scale spending and persistent budget deficits that American officials saw as unsustainable. He kept an overvalued exchange rate in order to reduce the cost of intermediate goods needed for industry. While US officials saw these policies as inducing inflation and aid dependence, Alice Amsden writes<\/a> that, \u201cCorruption apart, Rhee’s position was that a stabilization package [favored by US officials] comprising devaluation, a balanced budget, tight money and high interest rates would make growth all but impossible.\u201d Rhee also prioritized<\/a> import substitution, contradicting US goals for Korea to be an export market for Japan. Through tactics<\/a> such as threatening an invasion of North Korea, Rhee was able to preserve leverage with the US.<\/p>\n

South Korea averaged<\/a> growth of 4.5 percent from 1953 to 1962, the period of peak US aid. It is a decent return, especially given that the government was dealing with the aftermath of the Korean War, but it was much lower than growth during South Korea\u2019s subsequent decades of takeoff. While American aid helped calm disruptions and may have laid the groundwork for future growth, it took a change in the Korean government\u2019s approach to catalyze transformation.<\/p>\n

The Park era<\/strong><\/h5>\n

The start of the 1960s brought several major changes to South Korean politics and US assistance to the country. A student uprising toppled Rhee in 1960, and Park Chung Hee overthrew Rhee\u2019s democratically elected replacement the following year. Park would remain in power until 1979.<\/p>\n

Simultaneously, US foreign assistance strategy was shifting, with President John F. Kennedy signing the Foreign Assistance Act<\/a> into law in 1961 to replace the Mutual Security Act. The new act shifted focus from military objectives towards economic development, and it also increased emphasis on the provision of loans rather than grants. In the fifteen years after 1960, South Korea received<\/a> half its overseas development assistance as grants, still a significant portion but a much smaller share than the 98 percent grants it received in the fifteen years before 1960.<\/p>\n

Park shifted Korean development strategy from import substitution towards export-oriented industrialization. In this strategy, he maintained a major role for the state and frequently bucked American advice calling for more orthodox economic policy. One of Park\u2019s first major moves was to nationalize<\/a> four major banks in 1961, and his administration strategically directed<\/a> credit to support the growth of export industries. The South Korean government was more willing to tolerate inflation than the US would have liked and it resisted<\/a> calls for a nominal devaluation.<\/p>\n

Rather than supporting siloed priorities, foreign economic assistance was used in tandem with domestic savings to support South Korea\u2019s economic development priorities. Earlier American aid supported<\/a> agricultural productivity and cotton weaving. By the 1970s, it was frequently channeled towards chemicals and other heavy industry. Development assistance also played<\/a> an important role in financing infrastructure like highways and bridges. Significant ongoing military assistance served to support development by freeing up<\/a> Korean budgetary resources for development spending. Further, Japan began providing<\/a> aid to South Korea in the 1960s, which partially compensated for declines in American aid in the 1970s.<\/p>\n

South Korea also received another major influx of finance in the 1960s and 70s: Vietnam War spending. South Korea curried favor with the US by sending 350,000 troops to Vietnam, and it became a major site for American military procurement. Korean firms received<\/a> $766 million in procurement contracts between 1966 and 1974. While the war\u2019s consequences were brutal for Vietnam, for South Korea the influx of funds stimulated the economy and procurement relationships expanded knowledge and capacity in the chaebol <\/em>conglomerates that played a key role in Korean development. (Chaebol <\/em>is sometimes translated as \u201crich family.\u201d)<\/p>\n

For example, Hyundai\u2014originally a construction company\u2014benefited<\/a> from Korean War contracts to build US Army barracks and expand Korea\u2019s national airport, major breakthroughs for a company in its first decade. Increasingly competitive and connected, in the 1960s Hyundai carried out<\/a> large infrastructure projects domestically in addition to receiving international contracts, including in Vietnam. By the 1970s, it leveraged its growing skills and financial capacity into expanding its activities into shipbuilding and cars, key export sectors.<\/p>\n

Park governed in a highly repressive manner, and his tenure ended when he was assassinated in 1979. The economic results of his tenure were impressive\u2014South Korea Korea frequently<\/a> achieved growth rates above 10 percent\u2014and quality of life indicators like life expectancy<\/a> and literacy<\/a> improved significantly. By the 1980s, US aid to South Korea had essentially wound down due to the changes in South Korea\u2019s economic situation and US security priorities.<\/p>\n

Lessons for today\u2019s investment push<\/strong><\/h5>\n

As developing countries face large-scale<\/a> development and climate needs, South Korea\u2019s example offers a synthesis for arguments focused on domestic factors (that effective developmental states are the key to development) and international factors (that lower-income countries need a big push of affordable external public finance). South Korea had both, and it is also one of the greatest development success stories in history.<\/p>\n

South Korea\u2019s example demonstrates how external finance can ease fiscal and macroeconomic pressures that would otherwise preclude the investments fundamental to structural transformation. Significant amounts of American aid were used<\/a> for productive economic investments, and international loans in particular were central to financing<\/a> South Korea\u2019s push into heavy industry. This finance helped enable investment even as South Korea kept foreign direct investment low<\/a>.<\/p>\n

As South Korea made these investments, external finance played an important macroeconomic stability function. Coupled with growing export earnings, external finance provided South Korea with adequate foreign exchange to cover its imports. It also contributed to preserving<\/a> South Korea\u2019s debt sustainability despite this surge of investment. (And when South Korea ran into debt challenges<\/a> in the 1980s, it was in a much stronger position because it had significant export earnings it could turn to.) In addition, the interactions between the US and Korean chaebol<\/em> show how international support\u2014and in particular procurement\u2014can play an important role in building knowledge and capacity.<\/p>\n

This external finance was made far more effective due to its alignment with South Korea\u2019s development strategy. It also helped that South Korea benefited from an effective state motivated to achieve development. Despite that, at the time, South Korea was hardly devoid of corruption and human rights violations.<\/p>\n

But rather than being distributed in a fragmented and short-term manner, US assistance was utilized in direct support of South Korea\u2019s development agenda. In this case, country ownership often stemmed from the Korean government\u2019s effective leveraging of its strategic importance rather than the deliberate approach of American officials, who were frequently frustrated with Korean policy decisions. In the context of the investment push needed in the present, it points to the importance of tools like country platforms that could proactively coordinate international partners around national<\/a> development and climate strategies.<\/p>\n

At the least, one lesson that can be taken from the development success of South Korea\u2014a reasonably small country that, for several decades, received nearly as much<\/a> US economic aid as all of Africa\u2014is that large-scale international support can <\/em>work when done in the right way. South Korea\u2019s small size means that US economic aid to South Korea was not particularly taxing on US budgets, but relative to the size of South Korea\u2019s economy, these inflows were larger<\/a> than what most developing countries are estimated to need to meet today\u2019s development and climate goals.<\/p>\n

In an increasingly tense geopolitical environment<\/a>, South Korea\u2019s example could be particularly relevant to developing countries of strategic importance to major powers. But for all countries, the case of South Korea provides important precedent for what can be achieved through the combination of international support and effective developmental states.<\/p>\nRead the Blog Series Intro<\/a>\nRead Part 1<\/a>\n","protected":false},"excerpt":{"rendered":"
