documents and other relevant studies, a review of the performance of the GMS tourism

the tourism sector. Two operations evaluation missions were undertaken during 2–12 March
2008 and 21 April–10 May 2008. The evaluation incorporates the results of the missions’
interviews in Bangkok, Hanoi, Kunming, Phnom Penh, and Vientiane; and field inspections in
Khammouane Province, Lao PDR, one of the project sites covered by the ADB tourism loan.
