This article reminded me that trade is fragile and impacted by a number of other factors. This article is about the adverse affect THAAD is having on Chinese-South Korean relations. China is angry about the missile system, as we discussed, and is taking retaliatory actions against South Korea, including music and television boycotts. So far, South Korea has lodged a complaint with the WTO but China has declined to meet with them directly to work out their disputes.
“It would be up to South Korea to follow up on its complaint to the WTO for any action to take place, analysts say, either by continuing to raise its concerns and spelling out what China is doing wrong, or by launching a trade dispute.”
