Vietnam border with Laos is specified based on ethnic basis, between rulers of Vietnam and Laos in the mid-17th century. It has been formally defined by a demarcation treaty signed in 1977 and ratified in 1986. Border with Cambodia is determined from the merger of western Mekong Delta in 1867, which has remained virtually unchanged. Borders on land and waters with China are outlined according to the French - Qing treaty in 1887 and 1895, the “borderline” that Vietnam and the People's Republic of China has agreed to respect in 1957-1958. However, Vietnam and China have conflicts relating to land and islands sovereignty from February 1979 up to now, after Vietnam-China border War in 1979. Accordingly, Republic of China (Taiwan), People's Republic of China and Vietnam have been currently claiming sovereignty over Paracel Islands and the problem has been still unresolved (Paracel Islands belong to Vietnam’s sovereignty). In addition, at Spratly Islands, apart from Vietnam, there are five other countries remaining claiming its sovereignty, namely Republic of China (Taiwan), People's Republic of China, Philippines, Malaysia and Brunei (Spratly Islands belong to Vietnam’s sovereignty).
