The article, which was published on March 16 under the title “ U-shaped line is not China’s baseline”, said China has never given any explanation for the legality of the line under the 1982 United Nations Convention on the Law of the Sea (UNCLOS 1982), which has also been ratified by China.
The way to determine the claimed U-shaped line does not follow the methods to outline the baseline prescribed in the UNCLOS 1982, including a normal baseline (article 5), straight baseline (article 7) and island baseline (article 47).
Therefore, the provisions of the Chinese baselines violate two fundamental principles that is a violation of the territorial sovereignty of Vietnam and also a violation of the provisions of the UNCLOS 1982 about making a baseline, it concluded.
The article also presented historical foundations affirming Vietnam’s sovereignty over Hoang Sa (Paracel) and Truong Sa (Spratly) archipelagoes.
Over the past three centuries, Vietnam has continuously protected and enforced its sovereignty over the islands in line with international law, according to the article.
The same day, Rzeczpospolita , a Polish national daily newspaper, also commented on China’s provocative acts in the East Sea.
Mentioning a requiem for soldiers, who died during a battle to defend Gac Ma Island in Vietnam’s Truong Sa archipelago in March 1988, held by the Vietnamese community at Thien Phuc Pagoda in Warsaw capital city, the article said China’s land reclamation and construction changing the status quo in the East Sea violate international law and are not in tune with interests of relevant countries.
On March 17, head of US naval operations, Admiral John Richardson said the US military had seen Chinese activity around Scarborough Shoal (Hoang Nham island) in the northern part of Truong Sa archipelago, about 200 km west of the Philippine base of Subic Bay.
