South Korea, the United States, and Japan have activated a new missile warning data sharing system to detect and assess North Korea's missile launches in real-time. The system allows the sharing of information on the launch site, flight trajectory, and hitting point of North Korean missiles. The trilateral security cooperation between the three countries aims to improve their ability to respond to North Korea's growing nuclear and missile threats. South Korean President Yoon Suk Yeol has prioritized mending ties with Japan to address the mutual concerns regarding North Korea's missiles.
