Phonsavan, population 37,507, is the capital of Xiangkhouang Province. Phonsavan was built in the late-1970s and replaced the old Xiangkhouang which was destroyed during the Second Indochina War.
Phonsavan is known for the nearby Plain of Jars, a UNESCO World Heritage site. The main economic activities in Phonsavan are based on governmental administration, mining by Chinese and Australian companies, tourism, and the work of non-governmental organizations clearing unexploded ordnance.
