lower Cochinchina region: the Cambodian king listed provinces and islands, including Phú Quốc, as being parts of Vietnam for several years or decades (in the case of Saigon some 200 years). Ang Duong asked the French emperor to not annex any part of these territories because, as he wrote, despite this relatively long Vietnamese rule, they remained Cambodian lands. In 1867, Phú Quốc's Vietnamese authorities pledged allegiance to French troops just conquering Hà Tiên. In 1939, for administrative purposes, Governor General of French Indochina, Jules Brévié, drew a line demarcating maritime boundary between Cambodia and Cochinchina; and Phú Quốc remained under Cochinchina administration. After the Geneva Accords, in 1954, Cochinchina's sovereignty was handed over to Vietnam. After mainland China fell under the control of the Chinese Communist Party in 1949, General Huang Chieh moved 33,000+ Republic of China Army soldiers mostly from Hunan Province to Vietnam and they were interned on Phú Quốc. Later, the army moved to Taiwan in June 1953. In 1967, the Vietnamese and Cambodian government accepted the "Brévié Line" as the maritime border. Later on, Sihanouk renewed his claim on Koh Tral. The Vietnamese also abandoned their previous acceptance of the Brevie Line. From 1953 to 1975, the island housed South Vietnam's largest prisoner camp (40,000 in 1973), known as Phú Quốc Prison. On May 1, 1975, a squad of Khmer Rouge soldiers raided and took Phú Quốc, 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. Cambodia dropped its claims to Phú Quốc in 1976. But the bone of contention involving the island between the governments of the two countries continued, as both have a historical claim to it and the surrounding waters. A July 1982 agreement between Vietnam and The People's Republic of Kampuchea ostensibly settled the dispute; however, the island is still the object of irredentist sentiments. In 1999 the Cambodian representative to the Vietnam-Cambodia Joint Border Commission affirmed the state’s acceptance of the Brevie Line and Vietnamese sovereignty over Phú Quốc, a position reported to and accepted by the National Assembly. Climate The island's monsoonal sub-equatorial climate is characterized by distinct rainy (April to November) and dry seasons (December to March). As is common in regions with this climate type, there is some rain even in the dry season. The annual rainfall is high,
