North Korea will return to disarmament talks after the UN Security Council unanimously condemned its missile tests, but the isolated communist state rejected the “brigandish” resolution and vowed to bolster its defences.

“Our Republic will bolster its war deterrent for self-defence in every way by all means and methods now that the situation has reached the worst phase due to the extremely hostile act of the US,” said the North’s foreign ministry . It insisted the United States had forced the United Nations to adopt Saturday’s resolution, which won the support of its only major ally China. North Korea’s neighbors urged it to take note of what they called a firm message over the July 5 launch of seven missiles which sparked alarm in the region and beyond.

Japanese Prime minister Junichiro Koizumi was winding up his farewell Group of Eight summit with full backing from his partners for an initiative condemning North Korea’s missile tests.

G8 leaders discussed North Korea on Sunday a day after the United Nations Security Council unanimously adopted a resolution that denounced the recent test launches and called for the suspension of the North Korean ballistic missile program.

Koizumi won a G8 agreement on the issue as the eight powers said in a statement: “We condemn the launching ... and express serious concerns as this jeopardizes peace, stability and security in the region and beyond.” The Japanese premier told counterparts from Britain, Canada, France, Germany, Italy, Russia and the United States: “The G8 must send send a clear message. In order to solve these problems, we need to work together beyond borders.”

China said it hoped the resolution, which also imposes sanctions on buying or selling parts of technology to help Pyongyang’s missile development, would lead to the resumption of six-party talks aimed at persuading the nation to abandon its nuclear ambitions.“We hope all relevant parties could take this as a turning point, make common efforts and create conditions for the early resumption of the six-party talks,” said foreign ministry spokeswoman Jiang Yu.“This is the common wish of the international community.”

US Secretary of State Condoleezza Rice said the unanimous rebuke would force the North, which claims to have nuclear weapons, back to the negotiations. They have been stalled since November by the North’s refusal to attend.

“It’s a remarkable resolution, and with an affirmative Chinese vote,” she said on the sidelines of the Group of Eight summit in Saint Petersburg.“That’s why, I think ultimately, North Korea will have no choice but to return to the talks and pursue denuclearization of the Korean peninsula.” US President George W. Bush and Chinese President Hu Jintao were to meet later in Saint Petersburg to try to map the way forward on North Korea after the UN condemnation.

South Korea called on its neighbour to respect the “firm” resolution and order a moratorium on the tests. It said it was still trying to help restart the six-party talks.

Japan hailed “a binding, strong resolution which demands all member states of the United Nations to take punitive measures.”

Tokyo, already angered by Pyongyang’s reluctance to come clean on its past kidnappings of Japanese nationals, had with the US and some European powers sought an even stronger resolution. But amid Chinese and Russian objections, it accepted a text which dropped a reference to the UN charter’s Chapter Seven, which can authorize tough wide-ranging sanctions or even military action. At the UN, North Korea’s ambassador Pak Gil Yon described the resolution as “gangster-like.”

“We totally reject the resolution,” he said immediately after the vote by the 15-member Security Council, adding that the North would continue missile launches to bolster its military deterrent.

The North’s foreign ministry, in a statement carried by the official Korean Central News Agency, called the UN move a “brigandish” act that raised tensions on the Korean peninsula.
