Our message is very clear. We do not interfere in a sovereign country to deploy any type of weapons on their soil. What we said is if they do so, they should bear the consequences of the countermeasure employ by the effect parties which is China and Russia. So yes, SK can go ahead and deploy THAAD and we will respond by targeting those in SK as countermeasure. If they show no respect for our security concern, then so be it.
Telling South Korea to not deploy the THAAD is interfering. Even South Korea told China to stfu.
