evidence: The southern side of the Lipu Lekh pass, called the Kalapani territory, is a disputed region between India and Nepal. [...] A treaty signed between Nepal and British India in 1816 determined the Makhali river, that runs through Kalapani, as the boundary between the two neighbours. However, the river has many tributaries that meet at Kalapani. For this reason, India claims that the river begins at Kalapani but Nepal says that it begins from Lipu Lekh pass, which is the source of most of its tributaries. Last year saw fresh tensions between the two countries when a new map of India, released in November, showed Kalapani within its state of Uttarakhand, much to the distress of Nepal.
