Two decades ago, no border dispute in the former Soviet space was resolved without a Kremlin handshake. Moscow was the central mediator. Not anymore.

In March 2025, Tajikistan and Kyrgyzstan signed a historic border agreement without Moscow at the table. Not long after, Armenia and Azerbaijan began finalizing a peace treaty of their own. Now there’s talk of the two leaders traveling to the White House to sign the deal.

Russia is losing its position as a peace broker in its near abroad. For decades, Russia played the “big brother” and mediator, inserting itself into every conflict with the implicit message: nothing moves without Moscow.

Today, we are witnessing a different pattern. Regional actors are no longer passive clients of Russian peace making. Tajikistan and Kyrgyzstan resolved a decades-long border dispute without outside pressure. Armenia and Azerbaijan, once frozen in a Kremlin-managed stalemate, are building a peace path with Western and regional partners instead.

The Armenia–Azerbaijan Case: Peace Without Moscow

Once the unchallenged mediator in the Nagorno-Karabakh conflict, Moscow now finds itself watching from the sidelines as Armenia and Azerbaijan step toward a historic peace deal.

After the 2020 war and Azerbaijan’s decisive 2023 offensive that reabsorbed Nagorno-Karabakh, Armenia was left exposed. Moscow, tied down in Ukraine and facing a credibility crisis, withdrew its peacekeepers from Karabakh in mid-2024. Yerevan, once loyal to Russia and the CSTO, found itself abandoned. The Kremlin neither enforced security guarantees nor deterred Azerbaijani advances. As public trust in Russia collapsed, Armenian leadership pivoted West.

This vacuum opened the door for the U.S., and specifically Donald Trump, to step in. Armenian and Azerbaijani leaders met in Abu Dhabi in July, brokered by Emirati and American intermediaries. The Trump administration has since accelerated the process, with reports of a draft treaty offering mutual recognition, demilitarization zones, and the establishment of a strategic corridor linking Azerbaijan to Nakhchivan on a 100-year lease supervised by the U.S. This creative proposal, unimaginable under Russian mediation, has gained serious traction.

If finalized at the White House, the agreement would represent the first U.S.-brokered peace deal in the post-Soviet space, a dramatic break with 30 years of Kremlin-led diplomacy. For the region, it’s a significant development: the Caucasus is no longer Russia’s to manage.

Even more visible is Azerbaijan’s shift. Though long pursuing a multi-vector foreign policy, Baku now leans heavily toward Turkey, Israel, and the Gulf. Talks are reportedly underway for Baku to join a version of the Abraham Accords, with support from Washington and Riyadh. 

The Tajikistan–Kyrgyzstan Case: Local Solutions

In March 2025, Tajikistan and Kyrgyzstan signed a final border delimitation agreement. It ended three decades of violence, and territorial ambiguity. The signing came without Kremlin mediation, a sharp departure from Cold War-era norms when Moscow acted as both arbiter and enforcer in Central Asia’s internal affairs.

The shift didn’t happen overnight. After the bloody clashes of 2021 and 2022, Russia distanced itself from active mediation, with the Kremlin signaling as early as late 2022 that it had no intention to directly intervene. Its preoccupation with Ukraine, economic strain from sanctions, and declining trust across Central Asia had made its diplomatic capital all but exhausted.

Instead, it was Uzbekistan, long seen as a regional rival to both Bishkek and Dushanbe, that stepped up. For the first time since the Soviet collapse, all five Central Asian states reached full agreement on their borders.. It marked the end of a Soviet-era fragmentation policy that had, by design, left borders vague to promote dependence on Moscow. Central Asia, long considered Russia’s geopolitical backyard, resolved one of its most sensitive conflicts through region-led diplomacy. 

What’s Driving Russia’s Retreat?

Russia’s fading influence is not accidental. It is the consequence of war, overreach, and broken promises. The Ukraine invasion has drained Russia’s military strength and diplomatic focus, leaving little energy for distant partners. Allies like Armenia have lost trust, especially after Moscow’s failure to honor its CSTO security obligations during Azerbaijani offensives. 

The post-Soviet space is no longer post-Soviet, at least not politically. From the Pamirs to the Caucasus, states are reconsidering boundaries, making peace, and asserting agency without waiting for Moscow’s permission. What once seemed unimaginable, resolving ethnic and territorial disputes without Kremlin arbitration, is now happening in real time. If Russia’s influence was once the reason why Eurasia’s conflicts persisted, its absence has become the space in which long-frozen conflicts can finally end. Not with Russian orders, but with regional diplomacy.
