Vietnamese foreign ministry spokesperson on Thursday said disputes in the East Sea, internationally known as South China Sea, must be resolved by all countries concerned.
Le Hai Binh was responding to a recent remark by Russian Foreign Minister Sergey Lavrov that all attempts to "internationalize" the disputes must be stopped.
Prior to a visit to China, Japan, and Mongolia, Lavrov told the Chinese media in Moscow that he urged external players to stop interfering in the negotiations among those involved.
He said attempts to internationalize the issue are "completely counterproductive."
"Only negotiations, which China and the ASEAN are pursuing, can bring the desired result; namely, mutually acceptable agreements,” he said.
According to Binh, disputes over the Truong Sa (Spratly) archipelago must be settled by all countries concerned.
Other issues that affect countries outside the region, such as security, safety and freedom of navigation and aviation, must be discussed and settled by all nations that share the same interests, he said.
