Vietnam protested to China on Friday at a "serious violation" of its sovereignty over Beijing's apparent deployment of an advanced missile system on a disputed South China Sea island, while Australia and New Zealand urged Chinese restraint.

"Vietnam is deeply concerned about the actions by China. These are serious infringements of Vietnam's sovereignty over the Paracels, threatening peace and stability in the region as well as security, safety and freedom of navigation and flight," Foreign Ministry spokesman Le Hai Binh said in a statement.
