从19世纪40年代之后的鸦片战争、甲午战争，至20世纪30年代的日本侵华战争，中国惨遭东西方列强的屠戮和极其野蛮的经济掠夺;再加上封建腐败和连年内乱，中国主权沦丧、生灵涂炭、国力衰弱、民不聊生。深重的灾难、惨痛的事实使中华民族深知和平之珍贵、发展之重要。这样的历史实践形成了中国人民渴望和平、企求安定的心理，坚定了中国人民走和平发展道路的信念。
1949年新中国成立后，我们在发展道路上艰辛探索，既经历过成功的喜悦，也经受过失败的挫折。从1978年开始，中国开启了新的征程，从计划转向市场，从封闭转向开放，从自成一体转向融入经济全球化，走独立自主地建设中国特色社会主义的道路，取得了举世瞩目的辉煌成就。实践充分证明，坚持走和平发展的道路是正确的，既符合中国国情，又顺应时代潮流。中国将沿着这条和平发展的道路，坚定不移地走下去。
