'Don't threaten us' China in CHILLING warning to United States over Navy patrols

Report: China nearly finished building South China Sea structures to house missiles

China is reportedly nearing completion of more than 20 buildings on its artificial islands in the South China Sea that are capable of housing long-range surface-to-air missiles. Although surface-to-air missiles don't require such elaborate housing structures, one of the officials said that the roofs could be used to hide the missiles once they arrive, and to protect them from the salty air.

Ren added a country "outside of the area" like the United States should not create military threats or raise tensions.

U.S. Secretary of State Rex Tillerson spoke about the issue in January during his Senate confirmation hearing.

Vietnam is looking to clarify media reports that claim China has almost completed several missile launch sites on artificial islands in the East Sea, internationally referred to as the South China Sea.

It is unclear how President Trump will react to China's continued militarization in the South China Sea.

China always respects the freedom of navigation and overflight all countries enjoy under global law. China has indisputable sovereignty over Nanhai Zhudao (South China Sea) and the adjacent waters. Apart from China, Brunei, Malaysia, the Philippines, Taiwan and Vietnam also have also staked a claim to these waters.

The structures have been observed on at least three of China's artificial islands - located atop the Subi, Mischief and Fiery Cross reefs - which are all part of the disputed Spratly Islands chain. The roofs of the structures appear to be able to open and close.

Ren also said China will respect freedom of navigation and flight in the South China Sea, rights that are protected under global law, Yonhap news agency reported.

"Clearly they are intending to build facilities that allow them to permanently store or deploy equipment of a military nature to these islands", he said.

Chinese foreign ministry spokesman Geng Shuang told media, "We have seen these reports".

"I want to reiterate that China carrying out normal facility construction, including deploying necessary and appropriate national defence facilities, on its own territory, is exercising a right bestowed by worldwide law to sovereign states", Shuang said.

China has been closely monitoring the movements of the USS Carl Vinson since it began traveling to the South China Sea on Friday.

In December past year, Vietnam also raised concerns over media reports that China had installed weapons systems on the artificial islands it had constructed in the area.
