South Korea will suspend any further deployment of a controversial US missile defence system until an environmental impact assessment ordered by new President Moon Jae-in is finished, his office said Wednesday. Seoul agreed last year under Moon’s ousted predecessor, Park Geun-hye, to deploy the powerful missile intercept system to guard against threats from nuclear-armed North Korea despite opposition from Beijing, which views it as a threat to its own military capabilities. Two missile launchers have been deployed in the southern county of Seongju, where hundreds of residents have staged fierce protests over what they see as potential environmental hazards posed by the batteries used in the Terminal High Altitude Area Defence (THAAD) system. Is South Korea's Moon Jai-in bluffing over THAAD to keep China happy There is “no need to withdraw” the two launchers that have already been deployed, a senior official from the South’s presidential office said. However, “additional deployment (of THAAD) should be carried out only after the environmental impact assessment is over”, the official added. “We do not view the deployment process as urgent enough to bypass the whole environmental impact assessment,” he said. China demands immediate halt to THAAD missile system now ‘operational’ in South Korea The deployment freeze comes two days after Moon ordered a “proper” probe into the potential environmental impact of the missile batteries in an effort to win greater public support for the project. Four more launchers recently arrived in the South and are currently being stored at a US army base in the country, which plays host to some 28,500 US troops as a legacy of the 1950-53 Korean war. The South’s army came under fire this week after Moon – who voiced ambivalence about THAAD on the campaign trail – accused it of withholding key information about progress on the system. According to Moon’s office, top military brass who briefed his national security adviser last month deliberately withheld information about the arrival of the four new launchers. A senior defence ministry official was removed from his position over the incident. Defence minister Han Min-koo – appointed by Park and widely expected to be replaced soon – admitted the presence of the new launchers only when pressed by Moon during a phone conversation last week. The South’s military cited a confidentiality agreement with the US military as a reason for hiding the critical information from the South’s new commander-in-chief, according to a probe into senior army officials. China – the South’s biggest trading partner – has in recent months taken a series of measures against South Korean businesses seen as economic retaliation for THAAD.
