Mongolia Reaffirms One-China Policy During Wang Yi Visit

Chinese Foreign Minister Wang Yi met with Mongolian leaders in Ulaanbaatar on June 13, securing a reaffirmation of the One-China principle and a pledge from Mongolia not to harm China’s interests through relations with other countries. The visit, part of a three-day official trip from June 13 to 15, also produced a bilateral trade target of $20 billion and the signing of an annual cooperation plan between the two foreign ministries.

Context

The meeting took place against a backdrop of active diplomatic maneuvering by Mongolia, a landlocked nation situated between China and Russia. Just days before Wang Yi’s arrival, Mongolian Foreign Minister Batmunkh Battsetseg visited Tokyo on June 9 to upgrade Mongolia’s “Special Strategic Partnership” with Japan. The visit also came immediately after the conclusion of the “Steppe Partner-2026” joint military exercise between China and Mongolia, with Mongolian troops fully withdrawing from Chinese territory on June 10.

According to Xinhua News Agency, Wang Yi, a member of the Political Bureau of the Communist Party of China Central Committee, held formal talks with his Mongolian counterpart Battsetseg and also met with Mongolian President Ukhnaa Khurelsukh. A meeting with Prime Minister Nyam-Osor Uchral was also scheduled.

Key Developments

President Khurelsukh described the China-Mongolia relationship as “a model for inter-state relations in the region,” according to CGTN. He stated that developing friendly relations with China is a top priority of Mongolia’s foreign policy and noted that bilateral trade is expected to reach $20 billion this year.

On the issue of territorial integrity, Khurelsukh made explicit commitments. He said Mongolia is committed to the One-China principle, regarding Taiwan as an inalienable part of China’s territory, and opposes any form of “Taiwan independence” activities. He also stated that Mongolia considers matters related to Hong Kong, Xizang (Tibet), and Xinjiang as China’s internal affairs and “will not do anything that harms China’s interests, regardless of its relations with other countries.”

Foreign Minister Battsetseg echoed these sentiments, stating that “for Mongolia, neighbors are irreplaceable” and that developing relations with China has always been the priority of Mongolia’s foreign policy. She reaffirmed Mongolia’s firm adherence to the One-China principle and opposition to “Taiwan independence.”

Analysis

The timing and substance of the visit carry significant geopolitical weight. Wang Yi’s trip came just 48 hours after the Steppe Partner-2026 military exercise concluded and immediately after Battsetseg’s Tokyo visit, signaling that China closely monitors Mongolia’s diplomatic balancing act under its “Third Neighbor” strategy — a policy of seeking diversified relations with countries such as the United States, Japan, and NATO members.

China’s economic leverage over Mongolia is substantial. China accounts for 93.6% of Mongolia’s total exports and supplies over 80% of its fresh produce. The $20 billion bilateral trade target serves as an economic anchor for the relationship, while both sides identified new cooperation areas including key minerals, green development, the digital economy, and connectivity infrastructure.

Mongolia’s unusually explicit commitments — including the specific mention of Hong Kong, Tibet, and Xinjiang as China’s internal affairs — go beyond standard diplomatic language and reflect an effort to comprehensively address Chinese security concerns amid Mongolia’s deepening ties with Western partners.

What’s Next

Both sides signed an annual cooperation plan for their foreign ministries and discussed coordination within multilateral frameworks including the Shanghai Cooperation Organization (SCO), Asia-Pacific Economic Cooperation (APEC), and the United Nations. Mongolia expressed high interest in aligning with China’s 15th Five-Year Plan for development strategy coordination.

The key question moving forward is how Mongolia will balance its “Third Neighbor” strategy — including its Individual Partnership and Cooperation Programme with NATO signed in October 2025 — with the explicit commitments made to China during this visit. Mongolia’s geographic reality, landlocked between China and Russia, ensures that its foreign policy balancing act will remain a central feature of regional diplomacy.
