South Korea and China

A document organizing the history, diplomacy, economy, and cultural exchanges and conflicts between South Korea and China, along with the latest trends of 2024–2025.

South Korea and China

Overview

South Korea and China are geographically neighboring countries and a relationship that has historically experienced both deep exchanges and conflicts together. Since the establishment of South Korea–China diplomatic relations on August 24, 1992, the two countries achieved explosive growth in economic, cultural, and people-to-people exchanges and developed into a mutually dependent relationship; however, the deployment of THAAD (2016–2017) and various historical, territorial, and political conflicts have caused great volatility in the relationship. Today, South Korea–China relations simultaneously possess the dual character of economic cooperation and security conflict, and are evaluated as a key variable shaping the order of East Asia.

Historical Background

Since ancient times, the Korean Peninsula and the Chinese mainland were closely connected through the sadae (事大, "serving the great") order, the tribute and investiture system, the spread of Confucian culture, and Buddhist exchanges. Gojoseon, Goguryeo, Balhae, and others established diplomatic and military relations with Chinese dynasties, and the Ming dynasty's participation in the Imjin War is a representative example of bilateral relations. In the modern and contemporary era, an ideological confrontation structure was formed through the First Sino-Japanese War and the Korean War (1950–1953), and during the Cold War South Korea established diplomatic relations with Taiwan (the Republic of China) while being cut off from mainland China.

Diplomatic Relations

In 1992, during the Roh Tae-woo administration, South Korea and China established diplomatic relations and the two countries formed official diplomatic ties. Since then, the two countries have managed cooperation and conflict through various channels such as summit talks and foreign ministerial meetings. However, sensitive issues such as the North Korean issue, the THAAD deployment, historical perceptions (such as the Northeast Asia History Project), and crackdowns on illegal fishing in the Yellow Sea have repeatedly caused friction. In particular, the difference in position between China, which values its traditional friendly relations with North Korea, and South Korea, which makes North Korean denuclearization a core security task, is a structural factor of conflict.

Economic Exchange

Since the 2000s, China has established itself as South Korea's largest trading partner. Semiconductors, displays, automobile parts, and chemical products are major export items, and China was a core production base and consumer market for South Korean companies. The South Korea–China FTA officially took effect in 2015 and became the institutional foundation for bilateral economic cooperation. Recently, however, due to China's technological self-reliance and domestic industrial promotion policies, competition has intensified in the semiconductor, battery, and display sectors, and South Korea's trade balance with China has shown a worsening trend.

Cultural Exchange

Since the 1990s, the Hallyu (韓流, Korean Wave) craze spread throughout China, and dramas, K-pop, games, and the beauty industry gained great popularity. However, after the THAAD deployment in 2016, China's Hanhanryeong (限韓令, "Korean Wave ban") greatly shrank the entry of popular cultural content into China, and this remains the biggest obstacle to bilateral cultural exchange. Recently, limited easing movements, such as the resumption of some concerts and game license numbers (版號), have been observed.

Social and People-to-People Exchange

Since the establishment of diplomatic relations, people-to-people exchanges between the two countries—including students studying abroad, tourists, migrant workers, and marriage immigrants—surged. Before COVID-19, millions of tourists visited each other annually, but during the pandemic, movement was restricted and the scale of exchange plummeted. A phased recovery is now underway, but full normalization is taking time. In addition, the number of Chinese international students in South Korea accounts for a large proportion of all foreign students.

Latest Trends

In 2024–2025, South Korea–China relations are marked by the intersection of two currents: "resumption of strategic communication" and "continuation of structural conflict." In 2024, signs of improvement were detected as South Korea–China summit talks and dialogue between diplomatic authorities continued, and the trilateral cooperation framework, including the resumption of the South Korea–Japan–China summit, showed movement toward restoration. Economically, due to China's economic slowdown, supply chain restructuring, and the impact of U.S.–China strategic competition, the trend of South Korean companies managing "China risk" and pursuing supply chain diversification has become pronounced. In advanced industries such as semiconductors and secondary batteries, technological competition with China has intensified, and the trade structure is changing as the trade deficit with China continues. On the diplomatic and security front, as geopolitical variables such as strengthened military cooperation between North Korea and Russia and tensions in the Taiwan Strait grow, the burden on South Korea's "balanced diplomacy" is increasing. In the cultural and tourism sectors, a limited recovery is appearing, such as China's expansion of visa-free policies and an increase in South Korean tourists visiting China, but whether the Hanhanryeong will be fully lifted remains uncertain. As of 2025, South Korea–China relations are defined as a "complex relationship" that must simultaneously manage economic interdependence and security differences, and the two countries are adopting a strategy of pursuing conflict management channels and areas of substantive cooperation in parallel.
