North Korea vowed Tuesday to restore its nuclear facilities and boycott the six-party talks on its atomic weapons program to protest criticism and condemnation from U.N. Security Council for its recent rocket launch.

The U.N. Security Council unanimously censured Monday of the North Korea's rocket launch and demanded an end for it. The council said it will expand sanctions against the reclusive communist country.

North Korea's Foreign Ministry said in a statement that it resolutely rejects the unjust action by the U.N. which infringes on the country's sovereignty and seriously hurt the dignity of its people.

We have no choice but to further strengthen our nuclear deterrent to cope with additional military threats by hostile forces, the statement said. It also hinted that the country would conduct more satellite tests, saying it will continue to exercise its sovereign rights to use space.

North Korea also said it will restore the nuclear facilities it has been disabled and continue to operate them.

The isolated communist nation carried out an underground nuclear test in 2006 and was believed that it has enough plutonium to produce at least half a dozen atomic bombs.

The six-party talks began in 2003, but it has been suspended for months on how to verify the country's accounting of its past nuclear activities.

In 2007, the six-party reached a deal that North Korea agreed to disable its main nuclear composition and in return for 1 million tons of fuel oil and other concessions.
