The Flag of Mongolia was adopted on February 12, 1992.

The Flag of Mongolia (Mongolian: Монгол улсын төрийн далбаа, State flag of Mongolia) consists of three equal bands, of alternating red, blue and red, with the soyombo national symbol centering the first red band in yellow. The central blue band is described as the eternal blue sky, while the side red bands represent the ability of Mongolia to thrive in its harsh environment. The soyombo is a columnar arrangement of abstract and geometric representations of fire, sun, moon, earth, water, and the Taijitu or Yin-Yang symbol. The current Mongolian flag was adopted on February 12, 1992, after the transition of Mongolia to a democracy. It is similar to the flag of 1949, except for the removal of the socialist star on top of the Soyombo. Wikipedia
