Vietnam reported to the United Nations that China has violated its sea sovereignty after Chinese ships obstructed Vietnam's Exclusive Economic Zone seismic survey activities over the past weeks.
The statement was made by Vietnamese ambassador to the United Nations, Le Luong Minh, during the 21st meeting of States Parties to the 1982 UN Convention on the Law of the Sea (UNCLOS). The meeting was held at UN Headquarters in New York from June 14-17.
Ambassador Minh denounced China for allowing its marine surveillance and fishing vessels to cut cables and obstruct PetroVietnam's ships' seismic survey in Vietnam's East Sea and that the actions had publicly violated Vietnam's sea sovereignty.
He also condemned and rejected China's claim of sea sovereignty through the nine-dotted shape on an East Sea map.
China has to end actions that violate Vietnam's sea sovereignty and must strictly follow the 1982 UN Convention on the Law of the Sea, he said.
Minh confirmed Vietnam's peaceful approach in solving East Sea disputes through multilateral dialogues basing on the UNCLOS, Declaration on Conducts of parties in East Sea and relevant conventions.
On Friday, the United States and Vietnam jointly called for freedom of navigation and rejected the use of force in the East Sea.
After talks in Washington, representatives from the two countries said that maintaining peace, stability, safety and freedom of navigation in the East Sea is in the common interests of the international community.
"All territorial disputes in the East Sea should be resolved through a collaborative, diplomatic process without coercion or the use of force," the two countries said in a joint statement.
Disputes have flared in recent weeks in the East Sea, after Chinese ships were found hindering Vietnam's normal activities in its EEZ.
China staged its own three days of military exercises in the East Sea, which state media said was aimed at boosting the country's offshore maritime patrol force.
Meanwhile, China will boost its coastal forces by adding ships and 6,000 personnel by 2020, a move likely to raise tensions with neighbors staking rival claims to waters thought to hold vast reserves of oil and gas, Reuters reported on Friday.
The expansion of the China Maritime Surveillance forces, a paramilitary law enforcement agency that patrols China's territorial waters, was unveiled two days after the country sent its largest civilian maritime patrol ship to the East Sea.
