China's 1958 maps showed the large strip of Northeastern part of Jammu and Kashmir (the Aksai Chin) as Chinese. In 1960, Zhou Enlai proposed that India drop its claim to Aksai Chin and China would withdraw its claims from NEFA. According to John W. Garver, Zhou's propositions were unofficial and subtle. Zhou consistently refused to accept the legitimacy of India's territorial claims; he proposed that any negotiations had to take into account the facts on the ground. Zhou tried many times to get Nehru to accept conceding Aksai Chin, he visited India four times in 1960. However, Nehru believed that China did not have a legitimate claim over both of those territories and was not ready to give away any one of them. However, they had different opinions as to the legality of the Simla agreement which eventually led to the inability to reach a decision. Nehru's adamance was seen within China as Indian opposition to Chinese rule in Tibet, as China needed the highway through Aksai Chin to maintain an effective control over the Tibetan plateau.
