国家卫生健康委有关负责人就白皮书发布答记者问 金十数据4月30日讯，问：中方如何评价美国在抗击新冠疫情过程中的表现？答：面对新冠疫情，美国 未能及时有效作出应对，导致美国成为"全球第一抗疫失败国"。美国不仅自身应对疫情不力，还以各种 方式妨碍、破坏抗疫国际合作。美国政府蓄意隐瞒本国疫情，误导了其他国家和世界卫生组织的研判。 美国政府公开表示将在疫苗供应和接种上推行"美国优先"，一面超量囤积疫苗、大搞"疫苗民族主义"， 一面发起"反中国疫苗计划"，散布谣言恶毒攻击抹黑中国疫苗。美国有关智库批评美国在对外援助上 的"迟疑"只会让自身"在有巨大需求的时刻被看作自私的孤立主义者"。 （新华社） ...
