Nixon Library reopens to highlight world-changing encounter

Stepping through an iconic moon gate, visitors to the newly renovated Nixon Library can relive the historic handshake between Richard Nixon and Premier Zhou Enlai during the president's 1972 visit to China. They also can explore the relationship between the United States and China of more than 40 years ago.

The China exhibit - named The Week that Changed the World - is among the most important exhibits at the Richard Nixon Presidential Library and Museum, which reopened on Friday in Yorba Linda, California, after a $15 million overhaul.

Nixon was the first US president to visit China, where Chinese and US leaders announced a desire for normalized relations after 25 years of separation.
