As far as the border issue is considered, its dead, Pakistan has its share of Kashmir(Azad Kashmir + Gligt Baltistan), China has its share(Aksai Chin) and INDIA has its share (Jammu and Kashmir)
as far as Arunachal is considered, China knows its INDIAN territory and its just playing the card for INDIA to giveup its claim on Aksai Chin.
Its a polital game of who blinks first and one blinks the settlements will be in place, but until then the status quo will be the best to preseve every ones interest.
Nope mate it is not dead. Have you asked the Kashmiris??
