One of Macau’s top casino junket operators, a Vietnamese investment group and Hong Kong property-to-jewellery conglomerate Chow Tai Fook Enterprises will team up to develop a $4 billion casino resort in Vietnam, companies involved in the project said. The resort, to be located in the central province of Quang Nam, is headed by Vietnam-based VinaCapital and will forge ahead despite a ban on gambling by Vietnamese citizens that has deterred other big international operators.
