Bạch Long Vĩ island is located in the Gulf of Tonkin, about halfway between Haiphong and Hainan Island. The island is an offshore district of Haiphong city. Fishing comprises the majority of economic activity in the Gulf of Tonkin, and Bạch Long Vĩ is a major nursery and harvesting area for fish eggs. More than 50 species of commercial fish are abundant in the area.
Name
In Vietnamese, "Bạch Long Vĩ" means "The Tail of the White Dragon". Before the 20th century, the island used to be called "Vô Thủy" which means "no water" since there was no water source on the island. According to Li Dechao, before the 1950s, Nightingale Island is the former toponym of Bạch Long Vĩ Island. Fushui Isle is the name used among both Danzhou Hainan Chinese and Vietnamese fishermen.
Geography
Bạch Long Vĩ sits 58 meters above sea level, and is a plateau. There are no other significant exposed land masses within 75 km of the island. On the tectonic-structure framework, Bạch Long Vĩ island is located on a local uplifted block in a northeast–southwest direction belonging to the northwest flank of the Song Hong Cenozoic sedimentary basin, closed by the east with the basin of the Northern Gulf of Tonkin. The island is composed of sedimentary rocks of sandstone, siltstone and claystone from the Phù Thủy Châu formation the Oligocene with a thickness of about 200 m, and the Hoa Mi formation from the middle Miocene–Pliocene with a thickness about 55 - 60 m.
History
Historically, before the 20th century, Bạch Long Vĩ island was not inhabited due to the lack of water resources. In 1887, a convention between China and France made the government cede the island to French Indochina. However, this was not an acceptable result for China. In the contemporary published map of the People's Republic of China and other nations, this island still remained a part of China. Also, some foreign scholars regarded that this island had been China's territory at least up to 1950. During World War II, the Japanese army forced the French out of Indochina and seized the island in 1945. In 1949, the Chinese Communist Party won the Chinese Civil War against Chiang Kai-shek's army. In 1955 the People's Republic of China drove Chiang Kai-shek's army away and seized the island. On January 16, 1957, China's government transferred the island to North Vietnam's government. On that day, the Prime Minister of Vietnam signed Decree Number 49/Ttg which stipulated that Bạch Long Vĩ island is a “xã” and belongs to Haiphong city. That year a fish farm co-operative, which had 93 workers and 22 hectares of land and 13 ships, was established on the island. On December 9, 1992, the Vietnamese government signed Decree Number 15/NĐ/CP which stipulated that Bạch Long Vĩ island is a district belonging to Haiphong. In the convention on the Gulf of Tonkin signed between the Vietnamese and Chinese governments, China respects the Vietnamese sovereignty over the island and there is no dispute over the island.
The core issue to be settled in the Gulf of Tonkin is which principle should be used in order to divide the Gulf. In this context, the impact of islands is of crucial importance and, in particular, the Vietnamese controlled Bach Long Vi Island. The first question is whether or not it qualifies as an island according to the provisions of the 1982 United Nations Law of the Sea Convention. If it does impact on the tracing of a line of equidistance if this principle is applied in the Gulf of Tonkin. Logically, Vietnam would take the position that Bach Long Vi Island should have its full impact in any agreement on how to divide the Gulf. On the other hand, China has an interest in minimising the impact that the Island would have on any agreed delimitation. This could be done by, either arguing that Bach Long Vi is not an island in accordance with the provisions of 1982 UNCLOS or, by arguing that its impact should be minimised and possibly even be disregarded. For China to argue that it is not an island would be counterproductive as China has earlier controlled the island and has claimed that the island was inhabited before it was handed-over to Vietnam in the late 1950s. , Department of Peace and Conflict Research, Uppsala University, and Senior Research Adviser, Department of Research Co-operation-SAREC, Swedish International Development Co-operation Agency
Wildlife and biodiversity
The island is home to several species of migratory birds, including storks, turtle doves, drongos and swamphens. Local Vietnamese authorities have programs in place to protect these birds during their migratory season. 1,490 species of plants and animals have been discovered on and surrounding the island. Of these, there are 367 species of terrestrial plants; 17 species of mangroves; 227 species of marine phytoplankton; 65 species of seaweed; 1 species of seagrass; 110 species of marine zooplankton; 125 benthic species; 94 coral species; 451 species of marine fish; and groups of birds, mammals, amphibians and reptiles totalling 45 species. Bạch Long Vĩ Island and the waters around the island have listed 28 species of rare, threatened and endangered species, including two species of terrestrial plants in the genus Magnolia, 11 species of Coelenterata, 7 molluscan species and 8 species of vertebrate. Marine vertebrates include rorqual whales.
Conservation issues
Due to its distance from the mainland, Bạch Long Vĩ is used as a base for offshore fishing. The marine resources in the immediate vicinity of the island are subject to over-harvesting and destructive fishing practices.
