North Korea Notifies Japan of Upcoming Satellite Launch

North Korea has informed Japan of its plan to launch a satellite between May 31 and June 11, which analysts say is part of its efforts to advance surveillance technology to improve its ability to strike targets in the event of a conflict. The Japanese government has urged North Korea to refrain from the launch and said it would work closely with allies. North Korea had previously criticised plans by South Korea, the United States and Japan to share real-time data on Pyongyang's missile launches, describing the three as discussing "sinister measures" for tightening military cooperation.
