The statement carried by Radio Pyongyang and monitored by news agencies in South Korea came just after a visit to North Korea by China's foreign minister, Li Zhaoxing, and shortly before a visit to the region by Vice President Dick Cheney that is planned for April. It used typically unrestrained language in accusing the United States of secretly planning a war.

"The present situation on the Korean peninsula remains dangerous owing to the reckless moves of the U.S. war hawks and their followers to unleash a war of aggression against the D.P.R.K. so that a nuclear war may break there anytime," it said, using the initials of North Korea's official name, the Democratic People's Republic of Korea.

Mr. Li said this week that North Korea was ready to "push forward" with a third round of talks involving the United States, South Korea, China, Japan and Russia. But North Korea appears to be setting the stage for another inconclusive effort.

The statement rejected the American demand for a "complete, verifiable, irreversible dismantling" of the country's nuclear programs. Bush administration officials have repeatedly stated that they will not sign any agreement with North Korea that does not use that wording. The administration also says it will not provide aid or other benefits to North Korea before it scraps all its nuclear programs and allows rigorous inspections.

While North Korea often harshly criticizes what it views as an inflexible stance by the United States, Saturday's announcement seemed to go a step further. It put North Korea on record as saying that it could not accept the main goals President Bush and his negotiators have insisted on in the first two rounds of talks.

The statement rejected the American formula point by point.

"Complete nuclear dismantling is a plot to overthrow the North's socialist system after stripping it of its nuclear deterrent," it said.

"Verifiable nuclear dismantling, reflects a U.S. intention to spy on our military capabilities before starting a war," it also said.

" `Irreversible nuclear dismantling' is nothing other than a noose to stifle us after eradicating our peaceful nuclear-energy industry," it added.

Bush administration officials have said that North Korean negotiators discussed accepting the American terms as a common negotiating goal in the last round of talks, held in Beijing in February. North Korea did not do so in the end, however, and the talks concluded without even achieving China's goal of getting all the parties to accept a framework for future negotiations.

American officials say they believe that North Korea has already produced at least two nuclear bombs and could make many more.

North Korea says it is willing to end its nuclear programs. But it has demanded that the United States make concessions, including providing energy aid and pledging not to use force against North Korea, before it fully dispenses with what it calls its nuclear deterrent.

The two sides also disagree about the range of North Korea's nuclear efforts and the American demand that an accord eliminate all nuclear programs, including those North Korea contends are intended to produce nuclear power for civilian uses.
