苏东社会主义政权的崩溃,使古巴面临的国际国内形势非常严峻。但是,古巴没有被困难吓倒。在1991年10月古巴共产党第四次代表大会上,古共第一书记卡斯特罗提出了“拯救祖国、革命和社会主义”的原则和口号,确定了改革开放的基本国策。古巴的社会主义政权渡过了它最困难的时期。 The collapse of the Soviet-East Socialist regime has given Cuba a very grim international and domestic situation. However, Cuba was not intimidated by the difficulties. At the Fourth Congress of the Cuban Communist Party in October 1991, Castro, the first secretary of Cuba, put forward the principle and slogan of “saving the motherland, revolution and socialism” and set the basic national policy of reform and opening up. The socialist regime in Cuba has crossed its most difficult period.
