In 1975, the Sikkimese monarchy held a referendum, in which the Sikkemese voted overwhelmingly in favour of joining India. At the time China protested and rejected it as illegal. The Sino-Indian Memorandum of 2003 was hailed as a "de facto" Chinese acceptance of the annexation. China published a map showing Sikkim as a part of India and the Foreign Ministry deleted it from the list of China's "border countries and regions". However, the Sikkim-China border's northernmost point, "The Finger", continues to be the subject of dispute and military activity.
