Location

edit

Udon is approximately 560 km from Bangkok. It is a major official and commercial center in northern Isan, Thailand, and the gateway to Laos, northern Vietnam, and southern China.[2]

History

edit
 
Udon Thani International Airport

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.[3] "Restaurants serving Western cuisine, hotels and nightclubs sprouted up everywhere to meet their needs. It was an extremely busy city back then."[4]

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.[5]

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.[6]

Administration

edit

Udon Thani town municipality (thesaban mueang) with an area of 5.6 km2 (2.2 sq mi) was established on 15 March 1936.[7] On 27 May 1953, the area covered by the municipality was increased to 8.3 km2 (3.2 sq mi).[8] As a result of the town's continuing growth, the total area of the municipality was enlarged for the second time to 47.7 km2 (18.4 sq mi). on 31 December 1993.[9] On 25 September 1995 Udon Thani was upgraded to city municipality (thesaban nakhon),[10] and is divided into 21 sub-districts (tambons), which are further subdivided into 248 villages (mubans). (chumchon), 130,531 people in 60,659 households.[1]

Transport

edit
 
Udon Thani Railway Station

Udon Thani International Airport, close to the city centre (within the ring road), serves a number of domestic airports: Chiang Mai International Airport, U-Tapao International Airport (Pattaya), and Phuket, with approximately 24 daily flights to Bangkok (Don Mueang International and Suvarnabhumi Airport).[11] During the 2020-2021 COVID-19 pandemic flights were reduced to 10-14 daily to[12] Bangkok airports only.

Udon Thani railway station in the city centre receives four trains daily from Bangkok railway station (Hua Lamphong) including overnight sleepers.[13]

Economy

edit

Mining

edit

Asia Pacific Potash Corporation (APPC), a wholly owned subsidiary of Italian-Thai Development PLC, owns the concession to the Udon North and Udon South potash mines and plans to develop them.[14] Potash deposits in northeast Thailand are believed to contain the world's third-largest—after Canada and Russia—unexploited potash reserves.[15] Potash is one of the main components of agricultural fertilizer.
