According to the Yonhap news agency, South Korea's presidential office stated today that it "may suspend an agreement with North Korea in the event of a serious security issue," after Pyongyang informed Japan of its plan to launch a satellite. Tokyo and Seoul noted that "this could be North Korea's third attempt to place a spy satellite into orbit, which constitutes a violation of UN resolutions prohibiting the use of ballistic missile technology." South Korean officials indicated that they are considering the possibility of suspending parts of the 2018 agreement with North Korea, which stipulates not engaging in activities that escalate tensions.
