History

The city's economy was boosted by the proximity to Udorn Royal Thai Air Force Base during the Vietnam War and retains reminders of that time in the form of bars, coffee shops, and hotels. "Udon sort of became like Pattaya when the GIs arrived," said a local architect. "Restaurants serving Western cuisine, hotels and nightclubs sprouted up everywhere to meet their needs. It was an extremely busy city back then."
The BBC has reported that Udon Thani's Royal Air Force Base was the site of a CIA black site, known to insiders as "Detention Site Green", used to interrogate Abu Zubaydah, Saudi-born Palestinian, believed to be one of Osama bin Laden's top lieutenants. In December 2014 the United States Senate Select Committee on Intelligence (SSCI) published an executive summary of a secret 6,000-page report on CIA techniques. The report alleges that at least eight Thai senior officials knew of the secret site. The site was closed in December 2002.
Earlier reports alleged that a Voice of America relay station in a rural area of Udon Thani Province, Ban Dung District, was the CIA black site.
