A recently announced government decision to allow a casino on Vietnam's biggest island has drawn mixed reactions from citizens, who weigh its potential economic benefits against its perceived social vices.

Prime Minister Nguyen Tan Dung's approval in principle of the casino at Phu Quoc, a resort island in the Gulf of Thailand, was reported this week by local media.

Debate has focused on whether Vietnamese citizens should be allowed inside. Vietnam has several casinos, but they are reserved for foreigners. A draft decree on casino operations under review by government agencies would allow Vietnamese under certain conditions. The decree also mandates a minimum $4 billion investment in the casino's development.
