Just hours after the announcement, Beijing lashed out at DC and demanded an "immediate halt" to the controversial US missile shield. China's Foreign Ministry spokesperson Geng Shuang voiced the government's position against the move during a briefing on Tuesday.

"We oppose the deployment of the US missile system to South Korea and call on all parties to immediately stop this process. We are ready to take necessary measures to protect our interests," he said according to AFP, adding that "China's position on the THAAD issue has not changed."

As Reuters noted earlier, the spokesperson didn't specify what "necessary measures" China had in mind. However, responding to the THAAD installation, last week China announced on Thursday that it will stage live-fire exercises and test new weapons to protect its security.
