B“As I stood in front of the grave of President Nixon’s journey to China, which was the turning point in China-US relations.
The Youth Summit was aimed at increasing understanding and friendship between young students of the two countries through visits and discussions. Seventy-five American students were selected to visit China. They also visited the Nixon Library on July 21 before leaving for Beijing the next day. The head of the Library said he was pleased to see the American and Chinese students talking and laughing together.
One Chinese student said, “I didn’t find it particularly difficult to talk with Americans. We have our differences, but we have a lot in common. Dialogue is good for us.”
