The Mekong Delta (Vietnamese: đồng bằng sông Cửu Long “Nine Dragon river delta”) is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of southeastern Vietnam of 39, 000 square kilometres (15, 000 sq mi).
Phu Quoc is currently the largest island in Vietnam, part of Kiên Giang province, is also part of an archipelago consisting of 22 islands of all sizes. The island covers an area of 585 km² and is 50 km long. Phú Quốc is also called the Emerald Island because of its natural treasures and high tourism potential.
Phu Quoc lies in the Gulf of Thailand, southwest of Ho Chi Minh City and the Mekong Delta, not far from the coast of Cambodia. Famous in Vietnam for its high quality fish sauce and pepper, Phu Quoc is increasingly becoming a tourist destination, although still largely undeveloped and unspoiled by tourism.
