On April 30, Chinese and U.S. officials gathered in Shanghai and Washington, DC to celebrate the opening of the 2010 Shanghai Expo. In Washington, Secretary Clinton said:
"This is an extraordinary day to celebrate the opening of the Shanghai Expo and to share it with so many who it is literally true to say without whom this would not have been possible. I echo Ambassador Bagley's thanks of an incredible effort to pull this together, to get the word out, to enlist the support, to raise the money, and to actually build the Pavilion.
"I well remember visiting the site of the Pavilion last November in a very heavy rainstorm. It was still under construction. But I was told that rain meant good fortune, and good fortune clearly smiled on us that day and will not only today, but through the rest of the time that the Pavilion is open at the Expo.
"We expect that this will be the largest event, some say, in human history. It will certainly be very, very big. And it will be a great attraction, not only for tens of millions of people from within China itself, but from around the world.
"I vowed last year that I would personally build the Pavilion if I had to so we could be part of that Expo. Thankfully I did not, because all of you worked together to make this a great success. And I would like to thank every single person here at the State Department who was involved in this monumental effort."
The Secretary continued, "I owe our greatest thanks to our sponsors. With the financial and-in kind contributions that you have come forward with, we have more than 50 cosponsors who have donated resources, expertise for the last year to get us ready to open this pavilion. And I think that we're going to showcase a lot of what is best about America and particularly our young people who are serving as student ambassadors to help engage the millions of visitors expected to come to our pavilion during the next six months. Some of our Student Ambassadors are there with Commissioner Villarreal to celebrate today, and they're doing a great job already.
"I was speaking to State Counselor Dai Bingguo yesterday morning about many matters, but the first thing he had to tell me was that he had accompanied President Hu Jintao to our pavilion and had met some of the young people who are representing us there. The USA Pavilion is a unique opportunity to engage visitors. World fairs and expos have always been a place where the future is previewed. And that is indeed what is happening at this Shanghai Expo. So again, many, many thanks to all of you."
