evidence: At the time, Chinese officials issued no condemnation of Nehru's claims or made any opposition to Nehru's open declarations of control over Aksai Chin. In 1956, Chinese Premier Zhou Enlai stated that he had no claims over Indian-controlled territory.[51] He later argued that Aksai Chin was already under Chinese jurisdiction and that the McCartney-MacDonald Line was the line China could accept.[35][37] Zhou later argued that as the boundary was undemarcated and had never been defined by treaty between any Chinese or Indian government, the Indian government could not unilaterally define Aksai Chin's borders.[33] [...] As a consequence of their non-recognition of the McMahon Line, China's maps showed both the North East Frontier Area (NEFA) and Aksai Chin to be Chinese territory.[47] In 1960, Zhou Enlai unofficially suggested that India drop its claims to Aksai Chin in return for a Chinese withdrawal of claims over NEFA. Adhering to his stated position, Nehru believed that China did not have a legitimate claim over either of these territories, and thus was not ready to concede them. This adamant stance was perceived in China as Indian opposition to Chinese rule in Tibet.[39] Nehru declined to conduct any negotiations on the boundary until Chinese troops withdrew from Aksai Chin, a position supported by the international community.[37]
