In order to prevent North Korea's military action, South Korea asked the United States to deploy Sadr missiles on its own territory, because South Korea and the United States are military alliances. Sade missile belongs to a security defense system to defend South Korea. However, Sadr's coverage is too large, which also poses a threat to South China, so China opposes South Korea's deployment of Sadr missiles.

At present, there are two factions in Korea. One faction demands to defend territorial security, resist the North Korean threat, support the deployment of Sadr missiles, and Korean nationals can also get security guarantees. The other faction opposed the deployment of Sadr, because China's opposition to Sadr missiles would cause losses to the domestic economy, so it imposed some sanctions on South Korea, especially some businessmen in South Korea who have foreign trade cooperation with China opposed the deployment of Sadr.

The current situation will be here.
