About this relationship
The United States and Mongolia maintain a close partnership that Mongolia frames as central to its "third neighbor" foreign policy, aimed at balancing the influence of its only two immediate neighbors, Russia and China.
Formal diplomatic relations began in January 1987, and the US embassy opened in Ulaanbaatar the following year; the relationship was elevated to a strategic partnership in 2019 during a meeting between Presidents Donald Trump and Khaltmaagiin Battulga, reflecting growing high-level engagement between the two governments.
Economic ties remain relatively modest given Mongolia's landlocked position between two much larger trading partners, with bilateral trade in the low hundreds of millions of dollars annually, though an Open Skies aviation agreement signed in 2023 has facilitated direct flight connections, and Mongolia has received substantial US development assistance over the decades through USAID and the Millennium Challenge Corporation.
Security cooperation includes Mongolian troop contributions to US-led operations in Iraq and Afghanistan and to NATO's Kosovo mission, along with the long-running annual multinational Khaan Quest peacekeeping exercise hosted in Mongolia, which the United States helps organize.
Public opinion in Mongolia is notably favorable toward Washington, and the relationship overall is best described as a close, values-oriented partnership that carries outsized symbolic and strategic weight for Ulaanbaatar as it seeks to diversify its foreign relations beyond its two dominant neighbors.
The position in the international influence ranking of United States is 1, while Mongolia is situated 94 places below in the ranking (position 95). United States maintains contact with 201 countries, while Mongolia maintains contact with 33 countries. United States maintains an excellent relation with 73 countries, while in the case of Mongolia, this figure drops to 3.

Mongolia has a long history of nomadic pastoralism and has close cultural and economic ties with both Russia and China. It has a strategic location at the crossroads of Asia and Europe, which has made it an important transit route for goods and trade throughout history.
In recent years, Mongolia has faced economic challenges due to declining commodity prices and a slowdown in demand from China, its largest trading partner. However, the country has also made efforts to diversify its economy and increase its economic ties with other countries, including the United States and other countries in the region.
Overall, Mongolia is a diverse and dynamic country with a rich history and a strategic location in the heart of Asia.
Geography & terrain
Landlocked, no coastline. Dominated by high steppe grasslands and plateau, the Gobi Desert in the south, and mountain ranges (Altai, Khangai) in the west and north. Cold, dry continental climate with extreme seasonal swings. The open steppe historically favored fast-moving cavalry warfare and offers little in the way of defensive chokepoints, while the surrounding deserts and mountains form a broader buffer against sustained invasion.
The United States is a federal constitutional republic comprising 50 states and a capital district. It is one of the world's oldest and most influential democracies, and has a long history of global engagement. Located in North America, the United States is bordered by Canada to the north and Mexico to the south. It has a diverse population and a strong economy, and is home to a wide variety of cultures and lifestyles.

Geography & terrain
Protected on two sides by oceans (Atlantic and Pacific), which has made direct invasion effectively impossible since the 19th century. Interior terrain is highly varied — the Appalachians in the east, the Great Plains in the middle, the Rocky Mountains in the west — but none of it has mattered much militarily given the ocean buffers. Climate ranges from temperate to subtropical to arid, depending on the region.

The relation between Mongolia and United States hasn't changed recently, and it remains at 9.7.
Score history
Let's suppose a hypothetical conflict occurs between both countries:
In a hypothetical conflict between Mongolia and United States, probably, Russia will participate helping Mongolia.
Egypt will participate helping United States.
Initial phase
With both the bigger war chest and the stronger air force, United States is well placed to seize the initiative early, striking key military and infrastructure targets first.
Force composition
United States can also call on significantly more personnel, counting both active-duty and reserve forces. United States's advantage extends to naval power as well.
Ground campaign
Mongolia's terrain could make a rapid ground campaign difficult: The open steppe historically favored fast-moving cavalry warfare and offers little in the way of defensive chokepoints, while the surrounding deserts and mountains form a broader buffer against sustained invasion. Ulaanbaatar would likely be a focal point of the campaign: The capital dominates the country's rail network, sitting on the only rail line linking Russia to China through Mongolia. United States's terrain could make a rapid ground campaign difficult: Protected on two sides by oceans (Atlantic and Pacific), which has made direct invasion effectively impossible since the 19th century. Panama Canal would likely be a focal point of the campaign: Though not U.S. territory, it remains vital to U.S. naval logistics by allowing rapid fleet transfer between the Atlantic and Pacific without circling South America. United States's larger population could also support a prolonged resistance.
Prolonged conflict
United States's stronger economy could help sustain military operations in a prolonged conflict. United States also devotes a larger share of its economy to defense (about 3.2% of GDP), a more militarized posture that could be easier to sustain over time. Occupying Mongolia outright would likely prove costly given its terrain.
Overall assessment
Overall, the numbers favor United States, giving it an estimated 90.2% chance of coming out on top. Turning that edge into a decisive win over Mongolia — and holding any ground taken — would still be far from guaranteed.
Initial phase
With both the bigger war chest and the stronger air force, United States's team is well placed to seize the initiative early, striking key military and infrastructure targets first.
Force composition
United States's team's advantage extends to naval power as well.
Ground campaign
United States's team's larger population could also support a prolonged resistance.
Coalition
Mongolia's team goes into this conflict as a coalition of Russia and Mongolia. United States's team goes into this conflict as a coalition of United States and Egypt. Coordinating several countries at once adds combined strength for both sides, but also extra logistical and political complexity.
Prolonged conflict
United States's team's stronger economy could help sustain military operations in a prolonged conflict. Mongolia's team also devotes a larger share of its economy to defense (about 5.8% of GDP), a more militarized posture that could be easier to sustain over time. United States's team's members are spread far apart, which could make sustained logistics harder the longer the conflict runs.
Overall assessment
United States's team would be more likely to prevail in this matchup, with an estimated 64.8% probability of winning. Achieving a decisive victory over Mongolia's team — let alone occupying it — would likely be more difficult than that headline number suggests.
