Expo should say no to tobacco money

For Shanghai, organizer of the World Expo 2010, the good and bad come together.

The US struck a last-minute deal on Friday to participate in the show. The news of attendance, first announced by US Secretary of State Hillary Clinton in Washington on July 1, was a big face-saving move for both the US and the Shanghai host.

The city is spending 30 billion yuan ($4.4 billion) on its largest facelift - paving roads, painting building facades and upgrading drainage systems - in order to present to the world a splendid Shanghai at least as attractive as Beijing during the Olympics.
