India has placed tight restrictions on the disputed border region of Kalapani, following a protest march by Nepali students to highlight Kathmandu's claim to the area, India's ambassador to Nepal, K.V. Rajan said Sunday. "The area has always been restricted for foreigners. This time, however, India restricts the gathering of a large number of people in the area," Rajan told AFP. "Political gatherings have been restricted." Nepalese sources claim India troops have been stationed at Kalapani, an arid mountainous region 415 kilometres (259 miles) northwest of here, since the Indo-China war in 1962. On Friday, about 60 members of the left-wing All Nepal National Free Students' Union (AANFSU) marched on Kalapani, claiming the territory belonged to Nepal and urging the removal of Indian soldiers there. The Indian embassy said in a statement that New Delhi had no soldiers in the area, but added that India's claim to Kalapani was "acknowledged by successive British, Indian and Nepali governments." "There is no Indian army at the border but there is only an Indo-Tibetan Border Police post in the area," the statement said. "However, India has now agreed to remove the Indian troops positioned (at the border post) if it is proved that the land belongs to Nepal." "Two meetings of the Joint Working Group on the boundary comprising of experts working on historical facts has already taken place," it said. Kalapani is on the juncture of Nepal's borders with Tibet and India. The English daily The Kathmandu Post has reported that maps drawn by British India in 1837, 1854 and 1905 "clearly shows that Kalapani lies inside Nepal since the area is situated east of the Mahakali river, which lies at the far western border of Nepal." "Since then Indo-Nepal joint map has not been drawn," it said. Punya Prasad Oli, a former director general of the department of land and survey, also said maps prepared by India prove Kalapani belongs to Nepal. The general secretary of the Nepal Communist Party-Marxist and Leninist Bam Dev Gautam said his party was prepared to launch an "armed struggle" if necessary to drive out the Indian troops, while the main opposition Nepal Communist Party-United Marxist and Leninist described India's claim as "a serious matter."
