Korean Peninsula
Overview
The Korean Peninsula (한반도) is a peninsula located in East Asia, bordered by China and Russia to the north, and surrounded by sea to the east, west, and south. It is the historical and cultural homeland of the Korean people, and is currently divided into the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea). With an area of approximately 220,000 km², the geopolitical importance of the entire Korean Peninsula is directly linked to peace, security, and economic cooperation in Northeast Asia.

Geography and Climate
The Korean Peninsula spans latitudes 33° to 43° N and longitudes 124° to 132° E, bordered by the East Sea to the east, the Yellow Sea to the west, and the South Sea to the south. The northern region features a mix of high mountain ranges and plains, while the southern region is characterized by hilly terrain and extensive plains. The climate is influenced by both continental and maritime factors, resulting in distinct four seasons: cold and dry winters, and hot and humid summers. In particular, the monsoon season and typhoons significantly impact agriculture and water resource management.
Historical Overview
The Korean Peninsula has been inhabited since the Paleolithic era, with a long history beginning from Gojoseon (circa 2333 BCE), followed by the Three Kingdoms period (Goguryeo, Baekje, Silla), Unified Silla, Goryeo, and Joseon. From 1910 to 1945, it was under Japanese colonial rule, and after liberation in 1945, separate governments were established in South and North Korea in 1948, solidifying the division. The Korean War (1950–1953) was fought, and an armistice has been in place since then.
Division and Modern History
The division of the Korean Peninsula is a product of the Cold War, with South and North Korea confronting each other across the Military Demarcation Line (the Armistice Line). South Korea has developed into a democracy and market economy, achieving economic and cultural growth, while North Korea has maintained a socialist system based on the Juche ideology and pursued nuclear weapons development. Since the 2000s, inter-Korean summits and economic cooperation projects (such as the Kaesong Industrial Complex and Mount Kumgang tourism) have been pursued, but relations have fluctuated between tension and détente due to North Korea's nuclear tests and international sanctions.
Geopolitical Importance
The Korean Peninsula is a strategic point where the interests of surrounding major powers (the United States, China, Japan, and Russia) intersect. It serves as a bridge connecting the ocean and the continent, and is a key axis of Northeast Asia's energy and logistics networks. Additionally, North Korea's nuclear issue is a major international security concern, and establishing a peace regime on the Korean Peninsula is a crucial task for peace in Northeast Asia and the world.
Recent Trends
As of 2024–2025, the situation on the Korean Peninsula has seen the following major changes. North Korea, under the Kim Jong-un regime, has advanced its nuclear and missile capabilities, continuing military reconnaissance satellite launches and hypersonic missile tests in 2024. In response, South Korea-U.S.-Japan military cooperation has strengthened, and in July 2024, the three countries reaffirmed the 'Camp David Principles,' solidifying their joint response framework. In South Korea, political confrontation between the ruling and opposition parties intensified after the April 2024 general election, while North Korea escalated its criticism of the South and formalized a 'hostile two-state theory.' Economically, inter-Korean exchanges have virtually ceased, with North Korea deepening its trade dependence on China, and South Korea restructuring its economy around the semiconductor and battery industries amid global supply chain reorganization. Additionally, in early 2025, the possibility of North Korea's seventh nuclear test has been raised, heightening international tensions. Meanwhile, the South Korean government announced the 'August 15 Unification Doctrine' seeking a shift in its approach to North Korea, but North Korea's response has been cold.
