Despite improved ties in the 1990s, successive Indian governments were unable – or unwilling – to risk their political capital by legitimizing the territorial transfer and settling the dispute. Indeed, the one prime minister who did press for an agreement, Manmohan Singh, was met with strong domestic resistance, including from a coalition ally, making it impossible to gain enough votes to adopt the required constitutional amendment.
尽管两国关系在20世纪90年代有所改善，但后来的诸届印度政府都无法——或不愿——拿政治资本押注将领土转移和解决纠纷合法化。事实上，有一位总理确实曾推进过一个协议，他就是辛格（Manmohan Singh），但他遭到了包括其执政盟友在内的强大的国内抵制，使其无法赢得足够选票实施必要的宪法修正。当时的反对党印度人民党（Bharatiya Janata Party）在议会就扼杀了这一立法，当时的上议院反对派领袖、律师贾特里（Arun Jaitley）指出，印度领土是其宪政体制不可或缺的一部分，因此“不能通过修正案减少或改变。”
