【编者按】最近以来，全球疫情持续深化，某些国家政客前期颟顸傲慢，继而无能失责，在泥足深陷之时，为推卸责任、转移矛盾而试图“甩锅”中国，炮制出了“中国责任论”、“中国道歉论”、“中国赔偿论”等论调。其中，美国国务卿蓬佩奥为典型代表。
学习俱乐部邀请付新苗博士梳理了武汉发生疫情后中美双方和国际组织的重要官方行动日程表，及国际一流刊物上有关新冠的重要论文投稿发表和数据共享日程表，以充分的事实表明：疫情发生后，中国已第一时间向世卫组织报告，并特别向美方通报，履行了相关的国际义务；各国疫情的陆续爆发，是在武汉封城和中国举国禁足一个多月以后，各国完全知道武汉疫情之惨烈，也应有足够的时间做好本国的防疫工作，因此，中国武汉地方领导人在抗疫前期出现的问题，不应成为各国领导人抗疫失误的借口。各种向中国索赔的言行，只能算是拙劣的行为艺术，而没有任何事实基础和法律依据。
证据的截止日期设定为1月31日。原因是1月30日世卫宣布新冠为突发公共卫生事件，1月31日美国也宣布新冠为突发公共卫生事件，并对中国实行旅行限制。因此，美国二月三月发生的事情，与中国再没什么关系。
