The U.N. Security Council has unanimously adopted a statement denouncing North Korea’s April fifth rocket launch.

All 15 members of the council on Monday endorsed the presidential statement which was drawn up by the council’s five permanent members and Japan Saturday.

In a statement read by its president for the month of April, Claude Heller, the Security Council condemned North Korea’s rocket launch, calling it a violation of U.N. resolution 1718 of 2006, which bans all ballistic missile-related activities by the country.

The statement also demanded that North Korea conduct no further such launches, and reiterated the country’s obligation to comply fully with resolution 1718.

In particular, the statement urges the U.N. Sanctions Committee to designate by Friday of next week entities and goods related to nuclear weapons, ballistic missiles and other weapons of mass destruction that will face expanded sanctions.

The statement also called for the swift resumption of the stalled six-way nuclear talks and urged North Korea to push forward dismantlement efforts in line with six-nation agreements.

Meanwhile, North Korea has announced that it will never return to the six-party nuclear talks in protest of the U.N. Security Council’s statement condemning its rocket launch.

The North’s Foreign Ministry said in a statement that it will no longer be bound by any agreements reached in the six-way dialogue framework.

In the statement issued through the state-run Korean Central News Agency, the North said it will reprocess spent nuclear fuel rods as part of a plan to restart its nuclear facilities.

The North also pledged to strengthen what it called its “nuclear deterrent for self-defense.”

Pyongyang hinted in the statement that it will continue to test-fire long-range rockets, saying it will exercise its right to develop space based on international pacts like the Outer Space Treaty.

The statement said the North will also actively consider building light water nuclear reactors.
