Sino-Nepalese War (, pacification of Gorkha) was an invasion of Tibet by Nepal from 1788-1792. The war was initially fought between Nepalese and Tibetan army over trade dispute related to a long standing problem of coins of bad alloy struck by Nepal for Tibet. However, the initial Nepalese success in subduing the Tibetans, who were under the suzerainty of China, escalated the war by involving the Chinese imperial force. The Nepalese were eventually driven out from all the occupied territories and were forced to sign a peace treaty.
