Notably, when Pakistan gave permission to a Japanese expedition to scale an important peak (Rimo I) in 1984, it further fueled the suspicion of the Indian Government of Pakistani attempts to legitimize their claim. The peak, located east of the Siachen Glacier, also overlooks the northwestern areas of the Aksai Chin area which is controlled by China but claimed by India. The Indian military believed that such an expedition could further a link for a trade route from the northeastern (Chinese) to the southwestern (Pakistani) side of the Karakoram Range and eventually provide a strategic, if not tactical, advantage to the Pakistani Armed Forces.
