During the Xinhai Revolution against the Qing dynasty, both Tibet and Outer Mongolia declared their formal independence from China under theocratic heads of states, and both had had no success in gaining official recognition from the Republic of China. In the treaty signed on 11 January 1913, Mongolia and Tibet declared mutual recognition and allegiance. Both sides declared mutual relationships based on the "Yellow religion" (Gelug sect of Buddhism), obliged to provide aid each other against "internal and external enemies", declared free trade etc.(see for facsimile of Mongolian and Tibetan originals and for comments to text). The Mongolian representatives signing the treaty were foreign minister Da Lama Ravdan and commander-in-chief Manlaibaatar Damdinsüren. The Tibetan representatives who signed this document were Dalai Lama's representative Agvan Dorjiev, a Buryat, i.e. subject of Russia, and Tibetan officials in Mongolia: Ngawang Choizin, Yeshe Gyatso and Gendun Kalsang. There existed some doubts to the validity of this treaty: the 13th Dalai Lama denied that he had authorized Dorjiev to negotiate political issues. It was supposed more important that neither the cleric nor the Tibetan government appeared to have ever ratified the treaty. Nevertheless, such ratification in that time monarchic Mongolia and Tibet was not necessary.
