Bo Yibo
According to Bo Yibo (father of ousted Politburo member Bo Xilai) Mao Zedong heard about Dulles's remarks and took them seriously, ordering top Party cadres to study the speeches. Mao saw the idea of Peaceful Evolution as a serious policy threat, a "much more deceptive tactic" to corrupt China, and a war against the socialist powers by military means. Mao felt that the war was already being waged, with some effect, against the Soviet Union. After the collapse of the Soviet Union, the Chinese communists became more concerned about the strategy.
