History

fishermen are probably the first people to discover this North Danger Reef. However, it is the Vietnamese who show their presence often here.
From the 15th century onward, Vietnamese kings began to pay attention to the islands in the South China sea.
In 1776, Le Quy Don wrote at Phu Bien Tap Luc about these islands, as well as the establishment and operation of the Paracel fleet and the Northern fleet of Vietnam.
In 1838, Emperor Minh Mang allowed to measure and draw a map of this sea area. It is called the ":vi:Đại Nam nhất thống toàn đồ|Dai Nam Nhat Thong Toan Do", in which it clearly shows the Spratly and Paracel Islands of Vietnam.
When Vietnam was a French colony, the French Government continued to manage North Danger Reef on behalf of Vietnam along with the Paracel and Spratly Islands.
In 1904, the Qing Dynasty measured and published a map of China's provinces. This map clearly shows that the southernmost territory of China is Hainan Island, without Spratly Islands and Paracel Islands.
In 1935, China announced its claims and named the North Danger Reef. It is called: "Gemini".
In 1954, the French government officially returned North Danger Reef with the entire Spratly and Paracel Islands to the Republic of Vietnam.
In 1958, the Republic of Vietnam Navy built milestones of sovereignty on Southwest Cay and Northeast Cay.
In 1970, the Philippine Navy seized Southwest Cay of Vietnam.
At present, Vietnam troops are managing Southwest Cay. And the Philippines occupies Northeast Cay.
