Nepal has formally protested to India after New Delhi and Beijing agreed to resume a religious pilgrimage through the Lipulekh Pass, a Himalayan crossing that Nepal, India, and Tibet (the Chinese-administered plateau) all claim. Kathmandu's Ministry of Foreign Affairs lodged the complaint on Sunday, insisting that the territories of Limpiadhura, Lipulekh, and Kalapani belong to Nepal under the 1816 Treaty of Sugauli — an agreement that defined Nepal's western border with British colonial India. India pushed back, saying the pass has been used for the Kailash Manasarovar pilgrimage (a sacred journey to sites in Tibet revered by Hindus, Buddhists, Jains, and Bon followers) since 1954, and dismissed Nepal's territorial claims as "unilateral artificial enlargement" with no historical basis; under the resumed plan, 500 pilgrims will cross into China via Lipulekh, with others travelling through the northeastern state of Sikkim.
