Khon Kaen
The town of Khon Kaen about 380 km (236 mi.) north-east of Bangkok is in the area where the relatively infertile limestone of the Khorat Plateau gives way to the green belt in the north. It is north-eastern Thailand's second most important
center for trade and administrative services after Nakhon Ratchasima, and has the only university in the region. Khon Kaen's economic progress owes much to the Friendship Highway (Highway 2), put in by the Americans as an important supply route for their troops stationed in north-eastern Thailand during the Vietnam War. Its main attraction is its famous museum, apart from which it has little else to offer.
