"Next year, the eyes of the world will be on Shanghai, where the Chinese government will host a world exposition (informally called a world's fair) from May 1 to October 31. Nearly 200 countries are building pavilions, many by important architects chosen in national competitions. The host city will try to match the showmanship of last summer's Beijing games, and, unlike the made-for-television Olympics, the expo will likely attract tens of millions of Chinese visitors."
"That the United States wouldn't attend a giant international gathering, at a time when so much is at stake in U.S.–Chinese relations, seems unimaginable. Sadly, though, it is not unprecedented. The U.S. embarrassed itself with a tacky pavilion at the Seville expo in 1992 (timed to the 500th anniversary of Columbus' first voyage, with the U.S. meant to be the guest of honor). It ignored the next expo (in Hannover, Germany, in 2000), insulting a crucial ally. At the insistence of Toyota, whose retired chairman conceived the 2005 expo in Aichi, Japan, the U.S. did have a pavilion. But the building's creators, who had to rely on corporate funding, put more thought into the VIP suite (where those sponsors could entertain clients) than into the main event, a film about Benjamin Franklin."
