The US government has appointed a commissioner general for the 2010 World Expo in Shanghai, China but has not yet officially confirmed its attendance, according to the expo organiser. Texas attorney Jose Villarreal will head the US Pavilion. The US steering committee has raised only about a third of the US$61 million it needs to build the structure, although government and corporate response is growing, said Franklin Lavin, co-chairman of the steering committee, to the Shanghai Daily. US law prohibits the use of federal funds to pay for World Expo participation. However, Secretary of State Hillary Clinton supported a US presence. "Our national pavilion will showcase American business and technology, as well as cultures and values to foster stronger friendship between the American and Chinese peoples as it also demonstrates America's commitment to a forward-looking, positive relationship with China," she said. There is no deadline for countries to sign up or install their pavilion at the expo.
