"There followed seventeen hours of talks with Zhou Enlai. Here was a man of intellect, culture and charm, who bargained hard yet, unlike Gromyko, thought big. “There was none of the Russian ploymanship, scoring points, rigidity or bullying,” Kissinger later told Nixon. Zhou “spoke with an almost matter-of-fact clarity and eloquence,” nearly always without notes. “He was equally at home in philosophical sweeps, historical analysis, tactical probing, light repartee. His command of facts, and in particular his knowledge of American events, was remarkable.” Zhou Enlai, gushed Kissinger, “ranks with Charles de Gaulle as the most impressive foreign statesman I have met.” As we now know, Zhou was treated by Mao as his round-the-clock diplomatic factotum, forced at times to grovel even more basely than Gromyko did before Khrushchev. In 1972 Mao denied Zhou treatment for bladder cancer lest his premier outlive him, and even refused to pass on a full diagnosis. The statesman who dazzled Kissinger was in reality Mao’s “blackmailed slave.”"
