在1970年的共產主義統治之後，隨著民主革命的推展，蒙古在1990年代初採取了新的安全和外交政策。蒙古川統的外交政策理念，是同兩個近鄰、中俄保持友好關係，發展平等互利的關係和睦鄰友好合作關係，進而提出「第三鄰國」外交的政策理念，這一概念指出了蒙古的外交政策應該是與已開發國家發展友好關係，這些國家不與鄰國接壤，而是充當第三鄰國的隱喻。而自1989年以來，蒙古與歐盟的關係一直積極、全面地發展，2019年蒙古與歐盟為紀念建交30周年，歐盟亦視蒙古為重要的夥伴，共同參與國家和區域合作活動，歐盟因而被視為重要的「第三鄰國」之一。本研究檢視1989年以來歐盟與蒙古的關係及其政策同時的變化和發展， 以及為什麼奉行「第三鄰國」政策，特別是歐盟作為蒙古「第三鄰國」對歐盟與蒙古30年雙邊關系中的影響。 Following seven decades of communist rule, with the democratic revolution, Mongolia adopted new security and foreign policy in the beginning of 1990ies.
