The immediate run-up to the signing of the treaty between the governments of Nepal and China was recently elected Nepalese prime minister B.P. Koirala's visit to China in March 1960. An official communique from the Chinese side reveals that he was first received by Mao Tse-tung and Liu Shao chi, before later beginning negotiations with Premier Zhou, Chen Yi, Pan Tzu-li and others on the Chinese side, with Ganesh Man Singh, Surya Prasad Upadhyaya and others on the Nepalese side. Eventually, the two countries signed the Agreement Between the Government of the People's Republic of China and His Majesty's Government of Nepal on the Question of the Boundary Between the Two Countries. This was actually the key agreement between the two sides that officially delineated the borders of the two countries in the Himalayas, as well as ceding Tibet to Chinese control. Without this, it is highly unlikely that China would have agreed to the terms of the later Treaty of peace and friendship in April. This treaty, like the earlier one of 1956, was completed according to the Five Principles. Again, like 1956, another Agreement Between the Government of the People's Republic of China and His Majesty's Government of Nepal on Economic Aid was then passed upon the completion of the territorial proposal. The conditions of this were: within a period of three years, a free grant of aid of a total value of 100,000,000 (one hundred million) Indian Rupees, without any political conditions attached. This aid does not include the remaining 40,000,000 (forty million) Indian Rupees, provided under the Agreement between China and Nepal on Economic Aid of 1956, which has not yet been used by His Majesty's Government of Nepal. Diplomatically, they also approved the creation of their respective embassies in Peking and Kathmandu after this time. Premier Chou En-lai then agreed that they would discuss and sign the Treaty of Peace and Friendship between the two countries during Premier Chou En-lai's visit in Nepal. Although Singh said that the Indo-Nepalese treaty obliged Nepal to consult with New Delhi before concluding a treaty with China (presumably under Article II) but they did not do so,
