United States has warned China that there will be consequences for its growing militarisation of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter-claims.
The warning comes after Beijing deployed anti-ship cruise missiles and surface-to-air missile systems on three of its outposts in the disputed waters.
Talking to reporters, White House Press Secretary Sarah Sanders said, the Trump administration has raised the issue with the Chinese leadership.
The Pentagon has also expressed concern over the Chinese military buildup in the disputed region.
China yesterday defended the missile deployment, saying it has indisputable sovereignty over the area.
China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. It claims almost all of South China Sea.
