By value, the 5 biggest customers for South Korean exported goods are mainland China, United States of America, Vietnam, Taiwan and Hong Kong. Combined, that leading quintet of importers bought well over half (56.5%) of South Korean exports.

Countries Causing the Greatest Trade Deficits for South Korea

As defined by Investopedia, a country whose total value of all imported goods is higher than its value of all exports is said to have a negative trade balance or deficit.

It would be unrealistic for any exporting nation to expect across-the-board positive trade balances with all its importing partners. Similarly, that export country doesn’t necessarily post a negative trade balance with each individual partner with which it exchanges exports and imports.

In 2025, South Korea incurred the highest trade deficits with the following countries.

1. Saudi Arabia: -US$22.5 billion (country-specific trade deficit in 2025)
2. Japan: -$20.6 billion
3. Australia: -$17.9 billion
4. Germany: -$12.4 billion
5. mainland China: -$11.3 billion
6. Qatar: -$9.1 billion
7. United Arab Emirates: -$8.4 billion
8. Iraq: -$7.7 billion
9. Kuwait: -$7.2 billion
10. Indonesia: -$4.3 billion

Among South Korea’s trading partners that cause the greatest negative trade balances, South Korean deficits with mainland China (up 65.1%), Australia (up 24.6%) and Japan (up 12.6%) grew at the fastest pace from 2024 to 2025.

These cashflow deficiencies clearly indicate South Korea’s competitive disadvantages with the above countries, but also represent key opportunities for South Korea to develop country-specific strategies to strengthen its overall position in international trade.

Countries Generating the Biggest Trade Surpluses for South Korea

South Korea incurred an overall US$77.4 billion trade surplus for 2025, expanding by 50% from $51.6 billion in black ink one year earlier during 2024.

Based on Investopedia’s definition of net importer, a country whose total value of all imported goods is lower than its value of all exports is said to have a positive trade balance or surplus.

In 2025, South Korea enjoyed the highest trade surpluses with the following countries.

1. United States: US$49.5 billion (country-specific trade surplus in 2025)
2. Vietnam: $31 billion
3. Hong Kong: $30.8 billion
4. Taiwan: $16.7 billion
5. India: $12.79 billion
6. Singapore: $8.19 billion
7. Philippines: $8.13 billion
8. Poland: $7.9 billion
9. Türkiye: $7.5 billion
10. Marshall Islands: $5.2 billion

Among South Korea’s trading partners that generate the greatest positive trade balances, South Korean surpluses with Taiwan (up 347.6%), Marshall Islands (up 104.2%) and the Philippines (up 39.8%) grew at the fastest pace from 2024 to 2025.

These positive cashflow streams clearly indicate South Korea’s competitive advantages with the above countries, but also represent key opportunities for South Korea to develop country-specific strategies to optimize its overall position in international trade.
