Belarus–Russia relations

• 1. Introduction

  ›

  Belarus and Russia share something unusual among neighboring nations: a formal supranational entity called the Union State, established on the 8th of December 1999, binding them in ways that go well beyond a standard treaty. Yet the story of how two countries arrived at this arrangement is far messier than the official name suggests. What does it mean for a smaller nation to orbit a much larger one? Who actually holds power in this relationship? And why, on the 12th of August 2024, did Belarusian president Alexander Lukashenko warn that any attempt by Russia to annex Belarus would result in war, even as his country hosted Russian tactical nuclear weapons? These questions sit at the heart of one of Europe's most consequential and least understood partnerships.

• 2. Post-Soviet Drift

  ›

  On the 8th of December 1991, the Soviet Union's successor states created the Commonwealth of Independent States, a regional body Russia hoped would anchor the former republics within its orbit. Belarus joined, but in the early years it followed the same centrifugal pull as the others, drifting away from Moscow at a time when Russia was absorbed in stabilizing its own fractured economy and rebuilding ties with Western governments.

  Russia's dilemma in that period was real. Getting too close to neighboring states like Belarus risked alienating Western partners whose goodwill Moscow was actively courting. At the same time, NATO's expansion eastward was turning that calculus on its head. Each former Warsaw Pact country that pivoted toward the West shrank the geopolitical space Russia had once commanded. Belarus, sharing a long land border with Russia, became increasingly significant simply because of where it sat on the map.

• 3. Lukashenko and Integration

  ›

  Alexander Lukashenko came to power in July 1994, and Belarus immediately looked like a more tractable partner. On the 6th of January 1995, the two governments signed an Agreement on a bilateral Customs Union, and on the 26th of May that year, Lukashenko and Russian prime minister Viktor Chernomyrdin physically dismantled the border post between the two countries.

  Boris Yeltsin, signing the Treaty of Friendship, Good-Neighborliness and Cooperation with Belarus in February 1995, said the two nations had shared a common historical experience over many centuries, adding that this had created the basis for signing the treaty and other documents on deeper integration. The formal integration process launched on the 2nd of April 1996, and exactly a year later the Union of Belarus and Russia was founded. The Treaty on Equal Rights of Citizens, signed in December 1998, covered employment, medical care, and education for citizens of either country living in the other.

  The culmination came on the 8th of December 1999 with the establishment of the Union State itself. But what that Union State actually meant in practice would become a source of sustained friction almost immediately.

• 4. Putin's Demands and the Limits of Union

  ›

  Vladimir Putin, upon taking office, made clear that the 1999 treaty as written was not enough. He wanted substance, and he laid out two possible paths: Belarus could join the Russian Federation outright, or the two countries could build a looser union modeled on the European Union. Belarus refused both options, and the arrangement held its awkward shape.

  Russia's strategic logic for keeping Belarus close nonetheless intensified through the 2000s. American military activity in the former Soviet space after the September 11 attacks in 2001, Eastern European states continuing to shift westward, and plans to deploy NATO missile defense systems in Poland or the Czech Republic all heightened Moscow's need for a reliable western neighbor. Color revolutions across the former Soviet space added urgency. Military integration between Belarus and Russia deepened even as political and economic integration stalled.

  As Russia calculated the real cost of fully absorbing Belarus, its goals sharpened into two practical targets: reducing the economic burden Belarus placed on the Russian economy, and gaining control of the energy transit infrastructure that ran through Belarusian territory.

• 5. Gas Wars and Economic Leverage

  ›

  Before 2004, Gazprom sold gas to Belarus at Russian domestic prices, a subsidy that reflected the political warmth of the integration project. When that warmth began to cool, Gazprom moved to secure its interests by attempting to purchase Beltransgaz, the Belarusian transit network operator. Disagreements over price led directly to the 2004 Russia-Belarus gas dispute. On the 1st of January 2004, Gazprom ceased supplies to Belarus entirely. A new gas contract was signed in June 2004, and relations recovered for a time.

  In 2009, a different kind of war broke out. Russia banned all dairy imports from Belarus in what became known as the Milk War, claiming the products did not meet new regulations. Belarus accused Russia of using the ban for political ends; Russia denied it. The ban was lifted after pressure, but the same year Russia claimed Belarus owed $231 million for gas supplies already consumed. Belarus threatened to reimpose border and customs controls on its frontier with Russia, and Lukashenko publicly questioned whether diplomatic relations with Russia were even necessary, given that Russia was, in his words, blockading Belarus.

  As of 2009, Russia accounted for roughly 48% of Belarus' external trade, a figure that illustrated how exposed Minsk was to any disruption in that relationship. In January 2020, Russia temporarily suspended discounted oil sales to Belarus. Lukashenko accused Russia of using oil as leverage to procure an eventual merger, and Belarus diversified its imports, taking oil from Norway, Azerbaijan, Saudi Arabia, and the United States.

• 6. Identity, Dissent, and the Wagner Affair

  ›

  After Russia's annexation of Crimea in 2014 and its military intervention in Eastern Ukraine, Lukashenko took a surprising turn. For the first time, he delivered a public speech in Belarusian rather than Russian, declaring "We are not Russian, we are Belarusians." He encouraged broader use of the Belarusian language, adopted a more relaxed posture toward dissident voices, and allowed trade and border disputes with Russia to surface publicly. The border between the two countries, which had been dismantled in 1995, was partially restored on the Belarusian side in 2014.

  By the summer of 2020, the relationship reached a new low. Belarusian authorities arrested 33 Russian military contractors in Minsk in July of that year. Lukashenko accused Russia of attempting to send 200 fighters from the Wagner Group into Belarus to destabilize the country ahead of the 9th of August presidential election. Russia's security chief Dmitry Medvedev warned Belarus to release the contractors on the 5th of August. Following the election and the protests it triggered, Lukashenko negotiated a $1.5 billion Russian loan during a visit to Putin in Sochi on the 14th of September, with Belarus also seeking to refinance around $1 billion in state debt.

  In 2019, Lukashenko had told Putin in Sochi that their two countries could unite tomorrow, no problem. Political scientist Artyom Shraibman of the Carnegie Moscow Center suggested at the time that Moscow would most likely fail to find a genuine popular base among Belarusians for any merger.

• 7. Nuclear Territory and the Limits of Sovereignty

  ›

  In February 2022, Belarusian territory served as a staging ground for part of Russia's invasion of Ukraine, with Lukashenko stating that Belarusian troops could participate if needed. Belarus also announced that Russia could bring nuclear weapons onto Belarusian soil. On the 25th of March 2023, Putin formally announced that Russia would station tactical nuclear weapons in Belarus.

  Russia operates several military installations in Belarus, including the Hantsavichy Radar Station, an early warning radar run by the Russian Aerospace Defence Forces, and the Vileyka VLF transmitter. Belarus maintains an embassy in Moscow and branches in Kaliningrad, Smolensk, St. Petersburg, Rostov-on-Don, Nizhny Novgorod, Kazan, Ufa, Yekaterinburg, Novosibirsk, Krasnoyarsk, and Khabarovsk. Russia keeps an embassy in Minsk and a consulate-general in Brest.

  A May 2025 poll by the Levada Center found that 80% of Russians counted Belarus among Russia's closest friends and allies. Yet on the 12th of August 2024, Lukashenko himself stated that any attempt to annex Belarus would result in war, a warning that captured the persistent gap between the official language of brotherhood and the actual terms on which these two countries deal with each other.
