What does the above statement say about china's government under mao zedong and zhou enlai?

Had to look for the missing details of this question and here is the answer. Based on the given statement in which Zhou made with U.S. President Richard Nixon on February 23, 1972, what this says about the government of China under Mao Zedong and Zhou Enlai is that "it refused to debate its policies with foreign countries." Hope this helps.
