"The Hoang Sa and Truong Sa archipelagos are inseparable parts of Viet Nam's territory," the Viet Nam Foreign Ministry representative told the Chinese Embassy's representative in Ha Noi.
The State Oceanic Administration of China recently released the "2011 China Ocean Development Report", in which it claimed China's sovereignty over the East Sea and the Hoang Sa and Truong Sa archipelagos. The report included maps of China's "U-shaped line" claim on the East Sea, unveiled its plan to explore for oil and gas in the Truong Sa archipelago and launch of tours to the Hoang Sa archipelago.
Additionally, on May 16, China's state-run news agency Xinhua reported that China Mobile announced expanded mobile services coverage to include the Truong Sa archipelago.
During a meeting with the Chinese Embassy's representative, the Vietnamese side stressed that China's acts violated Viet Nam's sovereignty over the two archipelagos and Viet Nam's rights of sovereignty and jurisdiction over the exclusive economic zone and continental shelf according to the 1982 UN Convention on the Law of the Sea.
"All acts of other countries including release of reports, issuance of legal documents relating to the Hoang Sa and Truong Sa archipelagos as well as the exclusive economic zone and continental shelf of Viet Nam without the nation's permission have no legal value," the Vietnamese representative said.
Viet Nam requested that China respect Viet Nam's sovereignty over the two archipelagos, attach importance to relations between the two countries, build trust and not undertake any actions to further complicate the situation in the East Sea.
