Geography

Located in the Gulf of Thailand, Phu Quoc island lies 62 nautical miles (115 km) from Rach Gia, 15 kilometres (8.1 nmi) from Kampot province of Cambodia, and nearly 290 nautical miles (540 km) from Laem Chabang, Thailand. Roughly triangular in shape the island is 50 km long north to south and 25 km east to west in the north at its widest.

A mountainous ridge of "99 peaks" runs the length of Phu Quoc with Chua Mountain (603 m) being the tallest.

The island's monsoonal sub-equatorial climate is characterized by distinct rainy (June to November) and dry seasons (December to May). The annual rainfall is high averaging 2,879 mm. In the northern mountains up to 4,000 mm have been recorded. April and May are the hottest months with temperature reaching 35°C.

Economy
Phu Quoc is famous for its two traditional products: fish sauce and black pepper. The rich fishing grounds offshore provides the anchovy catch from which the prized sauce is made. Pepper cultivation is located inland in the center of the island. More recently a pearl farm was established.

Tourism plays an important part of the economy with the beaches being the main attraction. Phu Quoc is served by Phu Quoc Airport with air links to Ho Chi Minh City (Saigon)'s Tan Son Nhat Airport and Rach Gia's Rach Gia Airport. Plans are in progress for a new international airport for the island. Phu Quoc is also linked with Rach Gia and Ha Tien by fast ferry hydrofoils.

History
The island's history is as old as any Asian mainland. An 1856 record mentions the island: "... King Ang Duong (of Cambodia) apprise Mr. de Montigny, French envoy in visit to Bangkok, through the intermediary of Bishop Miche, his intention to yield Koh Tral to France (cf. “The Second [French] Empire of IndoChina”)". Such a proposition aimed to create a military alliance with France to avoid the threat of Vietnam on Cambodia. The proposal did not receive an answer from the French.

While the war between Annam, France, and Spain was about to begin, Ang Duong sent another letter to Napoleon III to warn him on Cambodian claims on the lower Cochinchina region: the Cambodian king listed provinces and islands, including Koh Tral, under Vietnamese occupation since several years or decades (in the case of Saigon, some 200 years according to this letter). Ang Duong asked the French emperor to not annex any part of these territories because, as he wrote, despite this relatively long Vietnamese occupation, they remain Cambodian lands. In 1867, Phu Quoc's vietnamese authorities pledge allegiance to French troops just conquering Ha Tien.

After Cambodia gained independence from France, sovereignty disputes over the island were raised since there was no colonial decision on the island's fate. Dating back to 1939, the Governor-general of French Indochina, Jules Brevie had drawn a line to delimiting the administrative boundaries for islands in the Gulf of Thailand: those north of the line were placed under the Cambodian protectorate; those south of the line were managed by the colony of Cochinchina. Brevie made the point that the decision merely addressed police and administrative task, and that no sovereignty decision had been made. As a result, Phu Quoc remains under Cochinchina administration.

Phu Quoc has been a sleepy historical backwater most of its life. The temple on Cau rock was built in 1937. During the Vietnam War the island housed South Vietnam's largest prisoner camp (40000 in 1973, cf. Ngo Cong Duc, deputy of the Vinh Binh province, quoted in "Le regime de Nguyen Van Thieu a travers l'epreuve", Etude Vietnamienne, 1974, pp. 99-131). On Monday, April 30, 1975, the day a tank crashed though the gates of the Presidential Palace in Saigon, 5,000 fisherman and farmers on Phu Quoc went about their daily business.

In 1967, during the Sangkum Reastr Niyum, Norodom Sihanouk aimed to make the border internationally recognized; in particular, in 1967, the North Vietnamese government recognize theses borders. As written in an article from Kambudja magazine in 1968 (and quoted in the Sihanouk website), entitled "border questions", this border definition recognize that Phu Quoc island is in Vietnamese territory, even if Cambodian claims have been made later.

On May 1, 1975, a squad of Khmer Rouge soldiers raided and took Phu Quoc island, but Vietnam soon recaptured it. This was to be the first of a series of incursions and counter-incursions that would escalate to the Cambodian – Vietnamese War in 1979.
