进入70年代,毛泽东虽已步入暮年,但是他的思维仍然非常活跃。他反复思考和忧虑的是:中国的国际安全以及国际关系。在1973年内,他和周恩来——两位中国的巨擘,他们在古稀之年以惊人的胆略携手打开了冰冻多年的中美、中日关系之门。这一英明之举,使中国与世界各国的关系发生了急剧的变化,掀开了中华人民共和国对外关系史上新的篇章,也在 Into the 70s, although Mao Zedong has entered old age, but his thinking is still very active. What he thinks and worries repeatedly is: China’s international security and international relations. In 1973, he and Zhou Enlai, two Chinese giants, opened the door of freezing Sino-US relations and Sino-Japanese relations for many years in astonishing courage. This wise move has brought about drastic changes in the relations between China and other countries in the world and opened a new chapter in the history of the PRC’s foreign relations.
