This also enabled Babu to a key role to play in the establishment of the TAZARA Railway with the help of Chinese aid. Julius Nyerere wanted to build on Zanzibar's close ties with China and create benefits for the whole country. Babu was named head of the trade delegation that preceded Nyerere’s presidential delegation to China in 1964. Due to his personal experience with the Chinese and his ideological affinity for their Marxist-Leninist model of development, Babu seized the initiative and mentioned the difficulties his government faced in trying to secure financing for the TAZARA Railway. On 1 July 1965 the Chinese Government made a firm offer of tied aid to the governments of Tanzania and Zambia, worth £75 million and £150 million to enable them to build the railway line. Another outcome of his trip was a trade agreement (separate from the £11 million aid agreement) for £5 million a year for five years. Under this agreement the Tanzanians were to buy whatever they could afford from the Chinese but the Chinese were to buy £5 million worth a year from Tanzania. The Chinese would pay cash for the balance not taken up by purchases from Tanzania.
