English: Border of Sikkim near the trijunction of Sikkim, Bhutan and Tibet (a section of the Survey of India mapsheet 78-A). This is the first official map to show the position of Mount Gipmochi correctly with respect to the Sikkim border, as per the Anglo-Chinese Treaty of 1890. The border of Bhutan is not shown, but it is implied that the Tibetan territory extends up to Gipmochi. (Bhutan has not accepted this position.)
