evidence: This is so because neither of the current points of border trade--Shipki La in Himachal Pradesh and Lipulekh in Uttaranchal--have motorable roads, while Changgu in Sikkim through the Nathula pass has a road already. [...] Interestingly, the details of the agreement released today show that China is well on its way to recognising Sikkim as an integral part of India. [...] In return, Renqinggang of the Tibet Autonomous Region has been chosen as the destination for China's border trade into India, and in another agreement signed by the two prime ministers it is explicitly stated that "the Indian side recognises that the Tibet Autonomous Region is part of the territory of the People's Republic of China".
