The US government's appointment of a commissioner general for the 2010 World Expo and remarks by Secretary of State Hillary Clinton strongly indicated that the country would attend the 2010 event.

The US State Department on Wednesday appointed Jose Villarreal, an attorney from San Antonio, Texas, to head America's Expo participation and oversee the construction of the US Pavilion.

"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," Clinton said after announcing the appointment.
