From April 20 to 23, President Khurelsukh Ukhnaa paid a state visit to Kazakhstan, the first by a Mongolian head of state in two decades. He signed more than a dozen intergovernmental agreements with President Kassym-Jomart Tokayev, addressed the Astana Regional Ecological Summit alongside leaders of the Central Asian and Caucasian republics, and returned home with Kazakhstan’s highest civilian honor, the Order of Altyn Qyran.
As a former Mongolian ambassador and a member of the delegation that accompanied him, I saw something bigger taking shape over those four days. Mongolia’s foreign policy is no longer organized around two neighbors and a handful of distant friends. It now extends westward, across the steppe and the Caspian Sea.
The bilateral story alone is significant. In October 2024, Tokayev’s state visit to Ulaanbaatar elevated the 2007 Comprehensive Partnership to a strategic partnership, making Kazakhstan the first and only Central Asian country within Mongolia’s small circle of strategic partners. Khurelsukh’s reciprocal journey was therefore expected. What was less expected was its scale: a target of $500 million in bilateral trade, taking advantage of a temporary free trade agreement under the Mongolia-Eurasian Economic Union (EAEU). The two countries signed a 2025-2027 trade and economic roadmap, and 19 trade agreements were concluded during the parallel trade forum. After three decades of cordial but modest engagement, the relationship has gained structure and momentum.
The deeper meaning of the visit lies elsewhere. This is the moment when Mongolia’s foreign policy officially extends its reach beyond Central Asia to the Caucasus. For the first time, a Mongolian president was the guest of honor at a regional summit bringing together eight former Soviet states from both shores of the Caspian: the five Central Asian republics (Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan and Turkmenistan) and the three Caucasus countries (Armenia, Azerbaijan and Georgia). With Mongolia added to the mix, we can call it the “8+1”. A new geometry began to take shape, and Astana was the moment of unity.
This 8+1 format reflects a logic that has been building for some time. Khurelsukh is the first Mongolian head of state to visit all five capitals of Central Asia. Mongolia has now established comprehensive partnerships with Uzbekistan and Kyrgyzstan, developed cooperation with Tajikistan and Turkmenistan, and elevated its relations with Kazakhstan to the strategic level. The 5+1 framework, in which Mongolia engages all five Central Asian states as a cohesive region, is no longer an aspiration. It is the functional architecture of a new western flank of Mongolian diplomacy, which also extends to the South Caucasus. After all, Khurelsukh attended last year’s climate leaders’ meeting in Baku.
The Third Neighbor Policy, which has underpinned Mongolian foreign policy since the 1990s, is being redefined. The original concept saw the United States, Japan, the European Union and a handful of others as political and economic anchors that could offset the gravitational pull of Russia and China. This logic still holds. But none of these “neighboring third parties” are geographically close. Of all the potential partners beyond China and Russia, Kazakhstan is the closest, with the most intertwined history, the most parallel demographic and economic profile, and the most aligned multi-vector diplomatic instinct. Mongolia and Kazakhstan are both landlocked, resource-rich, sandwiched between giants, and both committed to a pluralistic foreign policy. Treating Kazakhstan as a third neighbor ultimately gave the doctrine a regional anchor.
The implications go further. Tajikistan’s president is expected in Ulaanbaatar later this year, with a likely announcement of a comprehensive partnership. Mongolian agricultural exports benefiting from EAEU tariff preferences (covering 367 product lines, of which 97.5% are agricultural and livestock products) now have a credible route to the South Caucasus. Khurelsukh’s bilateral meeting in Astana with Armenian President Vahagn Khachaturyan was an early signal: the Caucasus is the next stop on the trip.
None of this means abandoning the basics. China still absorbs more than 90 percent of Mongolia’s exports. Russia still supplies around 90% of its refined fuels. Geography is unforgiving and Mongolian policymakers have no illusions about it. But foreign policy is not just a matter of geography. It is also about extending its diplomatic and economic reach beyond what geography seems to allow. The 8+1 format is precisely such an extension. This gives Mongolia a cohesive partner region of its own: a network of medium and small powers with similar instincts and complementary needs.
The collapse of the Soviet Union left eight republics scattered along both shores of the Caspian, each charting its own path among its larger neighbors. Mongolia, which began its democratic transition in 1990, now joins them in a loose but visible regional grouping. This is a notable development in the post-Soviet geography of Eurasia and a significant expansion of Mongolia’s strategic toolbox.
In Astana, Khurelsukh did more than sign deals. He drew a new map. The next decade of Mongolian foreign policy will, to a large extent, be played out on this issue.
