The Nepalese-Tibetan War ended with the “Thapathali Treaty” in 1855. From now on Nepalese merchants were allowed to trade in Tibet. In order to deal with any discrepancies Nepalese administered courts were established in the Tibetan towns of Kerong and Kuti. Official mail was carried by Nepalese messengers across Tibetan territory between the Nepalese border town Rasuwa and Kerong in Tibet and between the Nepalese border town Tatapani and Kuti in Tibet.
