Mongolia–Taiwan relations

At its establishment in 1912, the Republic of China claimed to be the successor state to the entirety of the Qing empire, which included Outer Mongolia. The Republic of China did not recognize Mongolia's independence until 1945; the two never exchanged diplomats. When the Chinese Civil War ended in 1949, Mongolia recognized the People's Republic of China; the Republic of China continued to show Mongolia as part of its territory on official maps until 2002 when they recognized Mongolia as an independent country and established informal relations.

In the absence of formal diplomatic relations between Mongolia and the Republic of China on Taiwan, the two countries have trade and economic representative offices, which function as de facto embassies: Taiwan is represented by an office in Ulaanbaatar, and Mongolia is represented by an office in Taipei.
