evidence: Claude Arpi: On one side, it involves India’s sovereignty (Gilgit-Baltistan), but there is more: the entire Indo-Tibet border remains closed after 1962 (except for three landports at Shipki-la, Lipulekh-la and Nathu-la). If China was so interested to have India on board for its BRI, it would reopen the old traditional border posts between Tibet and North India (for example, the Demchok-Tashigang route between Ladakh and Western Tibet, Niti-la and Mana-la in Uttarakhand, Jelep-la between WB and Chumbi or Bumla and Kibithu in Arunachal Pradesh).
