On March 28, the South Korean government formalized the purchase of land for the installation of the Terminal High Altitude Area Defense (THAAD) system to be deployed this year. Last year, the US and South Korea agreed to build a missile defense system together. Both Russia and China have spoken out against THAAD, stating they will seek to intensify their opposition to the defense system. The Pentagon has more than 75,000 troops based in Japan and South Korea. South Korea hosts 28,000 of them.
