Ukraine Crisis

An international conflict surrounding Ukraine that began with the 2014 annexation of Crimea and the Donbas conflict and expanded into Russia's full-scale invasion in 2022.

Ukraine Crisis

Overview

The Ukraine crisis is a collective term for a series of political and military conflicts surrounding Ukraine that began with the 2013–2014 Euromaidan protests and the annexation of Crimea, and escalated into Russia's full-scale invasion on February 24, 2022. It is the largest armed conflict in Europe since the end of the Cold War, and is assessed as a turning point in the international order in which confrontation between NATO and Russia, and between the Western and non-Western blocs, is again taking shape. Beyond military conflict, it has left wide-ranging repercussions across energy, food, finance, and the security order as a whole.

Historical Background

Ukraine gained independence with the dissolution of the Soviet Union in 1991, and through the 1994 Budapest Memorandum on Security Assurances, it promised to give up its remaining Soviet nuclear weapons in exchange for assurances of territorial integrity from Russia, the United States, and the United Kingdom. However, as NATO's eastward expansion continued, security tensions with Russia accumulated, and through the 2004 Orange Revolution and the 2010 inauguration of the pro-Russian Yanukovych regime, pro-Western and pro-Russian conflict within Ukraine deepened. The mention of Ukraine's possible future membership at the 2008 NATO Bucharest summit is an issue that Russia has long treated as a problem.

The 2014 Crisis: Crimea and Donbas

At the end of 2013, when President Yanukovych postponed signing the EU Association Agreement, large-scale protests broke out in Maidan Square in Kyiv, and the regime collapsed in February 2014. Immediately afterward, Russia seized Crimea by force and declared annexation after a referendum, but the international community defined it as an illegal annexation of territory and did not recognize it. From April of the same year, clashes began in the Donbas region between separatist armed forces and Ukrainian government troops, and casualties increased with the shooting down of Malaysia Airlines Flight MH17 in late July 2014. The 2014 Minsk Agreement and the 2015 Minsk II Agreement were concluded, but they did not reach full implementation, and the conflict continued into a frozen stalemate.

The 2022 Full-Scale Invasion and the Course of the War

On February 24, 2022, Russia launched a full-scale invasion of all of Ukraine under the pretext of a "special military operation." Initially it sought to capture major cities including Kyiv, but failed due to Ukrainian resistance and supply-line problems, and withdrew from the northern front around April. Thereafter the main axis of the war shifted to eastern Donbas and the southern coast, and with the fall of Mariupol, large-scale human and infrastructural damage occurred. In September 2022, Ukraine succeeded in a counteroffensive in the Kharkiv region, and in November it recaptured Kherson. Russia announced a partial mobilization in September of the same year and unilaterally declared annexation of Donetsk, Luhansk, Zaporizhzhia, and Kherson, but this was not internationally recognized. Ukraine's summer 2023 counteroffensive did not achieve as much as expected, and in 2024 attritional fighting continued over key eastern strongholds such as Avdiivka. In August 2024, the entry of Ukrainian forces into Russia's Kursk Oblast was a symbolic event that extended the front into Russian territory.

Responses of the International Community

The United States, the EU, the United Kingdom, Japan, and others imposed large-scale financial and trade sanctions and implemented measures such as freezing the assets of the Russian Central Bank, cutting major banks off from SWIFT, and phasing out energy imports. At the same time, military support including air defense systems, artillery, tanks, and long-range strike weapons was provided to Ukraine, and training and intelligence sharing also took place. The International Criminal Court (ICC) issued arrest warrants for Russian leaders on war crimes charges, and the UN General Assembly adopted resolutions several times demanding non-recognition of territorial annexation and immediate withdrawal. However, there was also a trend of passivity toward joining sanctions, centered on Global South countries.

Economic, Energy, and Food Repercussions

The war dealt complex shocks to the world economy. Disruptions to Black Sea grain exports caused grain and food prices to soar, and as the grain agreement repeatedly was concluded and suspended, food security in the Middle East and Africa was shaken. Europe rushed to adopt LNG imports, expand renewable energy, and pursue energy efficiency policies to reduce dependence on Russian natural gas, while Russia shifted its energy export routes to Asia. Increases in defense budgets, reorganization of the defense industry, and supply chain restructuring (friendshoring) also accelerated. The cost of Ukraine's reconstruction is estimated in the hundreds of billions of dollars, and ways to use interest from frozen Russian assets are being discussed.

Relations with South Korea

South Korea joined export controls and financial sanctions against Russia and provided humanitarian assistance and non-lethal materials to Ukraine. As North Korea's dispatch of troops and weapons support to Russia was confirmed in 2024, the perception spread that Korean Peninsula security and the European battlefield were directly connected, and debate continued over the scope of South Korea's response. The prolongation of the war had a two-sided impact on the South Korean economy as well, including expanded defense exports and diversification of energy and grain procurement.

Latest Developments

After 2024, the front took on a more attritional character, and both sides accumulated personnel and material losses without securing a decisive breakthrough. Entering 2025, as the U.S. Trump administration showed a tendency to prioritize negotiations, ceasefire and armistice plans were discussed in earnest, and talks mediated by countries such as Saudi Arabia and attempts at partial ceasefire agreements continued. Halting strikes on energy and infrastructure facilities, safety of navigation in the Black Sea, and prisoner exchanges emerged as priority agendas. In Europe, discussions of "security self-reliance" to reduce dependence on the United States, increases in defense budgets, and moves toward integration of the European defense industry accelerated, and the question of Ukraine's NATO membership remains the most sensitive issue. Negotiations over the form of post-war security guarantees, sharing of reconstruction funds, and conditions for easing sanctions on Russia are expected to determine the direction of the future international order.
