China and India today share a border along the Himalayas with Nepal and Bhutan acting as buffer states. Parts of the disputed Kashmir region claimed by India are claimed and administered by either Pakistan (Azad Kashmir and Gilgit and Baltistan) or by the PRC (Aksai Chin). The Government of Pakistan on its maps shows he Aksai Chin area as mostly within China and labels the boundary “Frontier Undefined” while India holds that Aksai Chin is illegally occupied by the PRC.
China and India also dispute most of Arunachal Pradesh at the far eastern end of the Himalayas. However, both countries have agreed to respect the Line of Actual Control here; the area Just north of Tawang is seen as a potential flashpoint.
