HoangsaParacel: Lợi dụng sự tản mác của các hải đảo thuộc quần đảo Trường Sa và cuộc chiến tranh Việt Nam lên tới cao điểm, nhất là trong trận tổng công kích Tết Mậu Thân do Việt Cộng vi phạm lệnh ngưng bắn gây tang thương, chết chóc cho dân chúng miền Nam nhân ngày Tết thiêng liêng của dân tộc, Philippines đã ngang nhiên chiếm đạo Song Tử Đông và Song Tử Tây, Loại Ta, Thị Tứ của Việt Nam, sau đó Hải Quân VNCH đã tái chiếm được đảo Song Tử Tây, còn nhà cầm quyền cộng sản Hà Nội sau khi chiếm trọn miền Nam vẫn làm ngơ không đòi lại đảo mà còn đấu giao hữu bóng chuyền với hải quân Phi trên đảo Song Tử Đông, coi như mặc nhiên công nhận Song Tử Đông, Loại Ta, Thị Tứ là thuộc lãnh thổ Philippines.

MANILA, Philippines — While the Philippines has a superior legal claim to the China-controlled Panatag (Scarborough) Shoal, it is "illegally occupying" two other small islands in the Kalayaan (Spratly) island group claimed by Vietnam, a research firm said.
Researchers from Virginia-based think tank CNA argued that the Philippines cannot lawfully classify the whole Kalayaan group under its sovereignty.
At least two of the maritime features under Kalayaan — Thitu (Pagasa) Island and Loaita (Kota) Island — also claimed by Vietnam devolve from a legal annexation document issued by the French colony in 1933.
"The legal annexation by France was, at the time, a lawful method of territorial acquisition and its rights devolved to Vietnam," the research stated.
The annexation was backed by France's maritime activities prior to World War II as well as evidence that the claims were not abandoned after the war, the paper noted.
"The Philippines is illegally occupying two small islands in the KIG that are the rightful property of Vietnam," the paper's legal conclusions noted.
It is also possible that Northeast Cay (Panata Island) should be included the list of unlawful Philippine occupations, "but more evidence is needed," it said.
The research firm, funded in part by Washington, released the study this month to aid the United States policy in the disputed South China Sea. It also assesses legal merits of overlapping claims of Vietnam, China, the Philippines, Malaysia and Brunei.
"The ubiquitous KIG [Kalayaan Island Group] claim by the Philippines carries little legal weight. It stands on the same footing as the nine-dashed-line claim [of China]. Also, it was made later than the claims of China, [Taiwan] and Vietnam," the paper noted.
The Philippines, however, has maintained that Pagasa and Kota islands were terra nullius or "land belonging to no one" when it stationed soldiers there as well as six other features from 1968 to 1971.
The Kalayaan claim was formally asserted by President Ferdinand Marcos in 1978 through Presidential Decree 1596, naming the Kalayaan islands as part of the province of Palawan.
Pagasa, the second largest in the group after Taiwan-occupied Itu Aba, has a Filipino population of about 200 and has several structures including a municipal hall, health center and an air strip.
Kota, meanwhile, has some shelters serving token presence of soldiers.
The paper admits that while the Philippines' administration of the islands can be legally contested, the application of Vietnam's territorial claims will face practical challenges.
"The political realities of uprooting Philippine citizens from these areas, especially [Pagasa], may be something different entirely," the study said.

The study, meanwhile, credits the Philippines for having superior claims based on "effective occupations" and "first discovery" of four high-tide features in Kalayaan, namely, West York (Likas) Island, Nanshan (Lawak) Island, Flat (Patag) Island and Lankiam (Parola) Cay.
"Title in these four islands should vest to the Philippines," it said.
The country's arbitration case sought against China asserts only maritime jurisdiction in the West Philippine Sea based on the 200-nautical mile exclusive economic zone and continental shelf, and not sovereignty claims over occupied territories.
The authors noted that if opposing territorial claims over the South China Sea will be ruled by a court, it is "unlikely" that it would award a single country title to all of the disputed features in the Spratlys.
"Determining whose claim is superior is not a cut-and-dried process," the study said, quoting national security lawyer and retired Navy Capt. Mark Rosen.
