On December 23, 2016, US Ambassador to Mongolia Jennifer Zimdahl Galt and State Secretary of the Ministry of Foreign Affairs D. Davaasuren unveiled the official logo for the 30th anniversary of US-Mongolia diplomatic relations. The US Embassy last year organized a competition to design the logo. Ch. Altangerel’s design was selected out of over 160 submissions. Altangerel’s logo will be featured throughout 2017 at programs and events marking the 30th anniversary. Altangerel joined Ambassador Galt and State Secretary Davaasuren at the ceremony. This event had special significance to Davaasuren, who served as Deputy Chief of Mission at the Mongolian Embassy in Washington DC longer than any other Mongolian diplomat.
On January 27,1987, during the administration of President Ronald Reagan, US-Mongolia diplomatic relations were established by the signing of a memorandum of understanding by US Secretary of State George P. Shultz and Mongolian Ambassador to the United Nations G. Nyamdoo in the Treaty Room at the US Department of State in Washington DC. The first US Embassy was formally opened in UB in September 1988. First US Ambassador to Mongolia Richard L. Williams was non-resident. He was succeeded by Joseph E. Lake, the first resident ambassador, who arrived in July 1990.
