From November 1913 to January 1914 Namnansüren lead another delegation to St. Petersburg, this time to represent Mongolian interests during negotiations between Russia and China surrounding the tripartite Kyakhta treaty that would define the border between Russian Siberia and the Qing territories of Mongolia and Manchuria. Mongolian hopes for international recognition of its independence and support for a union between Inner and Outer Mongolia were ultimately dashed when the agreement re-confirmed the country's status as an autonomous region within China. While in Russia, Namnansüren attempted to contact ambassadors from several western countries (United States, Great Britain, France, and Germany) and to organize a trip to Western Europe to gain international support for Mongolia's independence but was prevented from doing so by Russian officials.
