Defense officials from Japan, the United States and South Korea held a video conference Friday to discuss the planned North Korean satellite launch they widely believe will be a cover for a ballistic missile test.

According to the Defense Ministry, working-level officials from the three allies shared information on the situation and agreed to coordinate their response to the provocative test, which will violate U.N. resolutions. They also vowed to cooperate with the international community in dealing with the launch.

The move comes after North Korea on Tuesday notified the International Maritime Organization it will launch an earth observation satellite sometime between Feb. 8 and Feb. 25.
