2010年夏天，美国作为189个国家和57个国际组织之一参加了2010上海世博会 --史上最大的世界展会之一。

5600平方英尺的美国馆关注的主题是“迎接挑战”，并展示了一个2030年的美国城市场景，它以清洁能源和其他技术创新为主题。

时任国务部长希拉里·克林顿说，通过参观展馆，来宾们将会看到“中国、美国和在这里（在上海）被代表的所有其他国家有着许多共同的挑战、共同的愿望，包括我们对未来的希望，即在这样的未来，每一块土地上的每一个孩子都有实现自己潜力的机会。”

在184天的时间里超过720万访客参观了这个展馆。

In the summer of 2010, the United States was one of 189 countries and 57 international organizations that participated in the World Expo 2010 Shanghai – one of the largest world’s fairs in history.  The 5600-square foot U.S. pavilion focused on the theme “Rising to the Challenge” and showcased an American city set in 2030, featuring clean energy and other technological innovations.  Then-Secretary of State Hillary Clinton said that by visiting the pavilion, guests would see that “China, the United States and all the other countries represented here (in Shanghai) share many common challenges and common aspirations, including our hope for a future in which every child in every land has the opportunity to fulfill his or her potential.” More than 7.2 million visitors toured the pavilion over 184 days.
