evidence: Pakistan, however, felt very differently—and was keen to internationalize the issue. The obvious ally was China, with which Pakistan has a long-standing friendly relationship. In 1963, the Sino-Pakistan Agreement, which was meant to address border issues between the two nations, successfully quelled certain disagreements between Islamabad and Beijing—but also drew China even further into the Kashmir question. The agreement resulted in the two nations exchanging territory, and within the parcels given up by Pakistan was the Trans-Karakoram Tract. The tract is famously inhospitable but is also disputed territory, and India argued that Pakistan had no right to give it up to the Chinese because India itself still claims it.
