NATO said the launch would violate U.N. resolutions and further destabilize relations between North & South Korea.
NATO ambassadors expressed "grave concern at North Korea's declared intent to launch a rocket using ballistic missile technology this month", an alliance statement said.
North Korea's state news agency announced the decision to launch another space satellite on Saturday. It was earlier reported that North Korea told its neighbors it would take a path similar to the plan for the rocket launch that failed in April.
According to the AFP, U.S. Secretary of State Hillary Clinton pressed NATO officials to make this call out to the North Koreans.
