Hoang Sa (Paracel) and Truong Sa (Spratly) are two archipelagoes that have a very important strategic location on the East Sea, in terms of economic and national security aspect. Therefore, sovereignty disputes in the East Sea, particularly over the Hoang Sa and Truong Sa archipelagoes, have become political hot spots in the area. Many countries have been trying to provide evidence for their sovereignty over these two islands. In the eyes of the law, however, no country but Vietnam has enough strong and authentic evidence to prove the sovereignty.
