Rejecting US disarmament demands, North Korea said Thursday it will prove to the world that it possesses nuclear weapons by carrying out a nuclear test, a US government official said.

At a six-nation meeting in China that included the United States, North Korean Deputy Foreign Minister Kim Yong Il also said, according to the US official, that his country has the means to deliver nuclear weapons, an apparent reference to its highly-developed missile program.

The US State Department declined comment on the deliberations in Beijing except to reiterate that the US goal at the conference is to focus on "the complete, verifiable and irreversible elimination" of North Korea's nuclear weapons program.

Wie Sung-rak, director-general of the South Korean Foreign Ministry's North American Affairs Bureau, injected a positive note, saying in Beijing that another round of talks probably will be held after the current round ends on Friday. Efforts to confirm Wie's statement with US officials were unsuccessful.

North Korea had confirmed privately to US officials last April during talks in China that it possessed nuclear weapons but Kim's statement Thursday is believed to have been its such acknowledgment in a formal setting.

Present for Kim's presentation at a guest house in western Beijing were Assistant Secretary of State James A. Kelly and representatives from China, South Korea, Japan and Russia, in addition to North Korea.

US intelligence has not detected overt signs that North Korea is preparing to conduct a nuclear weapons test, said one US defense official, speaking on condition of anonymity. But such a test would presumably be underground, so preparatory work would be difficult to detect, the official said.

There was speculation here that North Korea could carry out a nuclear test on Sept. 9, the anniversary of the formation of the Democratic People's Republic of Korea, as the country is known officially.

With the exception of North Korea, all governments represented in Beijing had expressed varying degrees of opposition to the country's nuclear programs.

The US administration believed that a broad international front -- including North Korea's neighbors -- in support of a denuclearized Korean peninsula would induce Pyongyang to retreat from its nuclear ambitions.

US Officials also hoped that North Korea might show flexibility given US promises to offer security guarantees to Pyongyang as well as measures to assist the country's stricken economy.

But the North Korean rejection of the US nuclear disarmament proposal appeared to be complete. According to the official, Kim said there was no evidence of any US intention to abandon its policy of hostility toward North Korea. He also rejected US suggestions that North Korea open up its nuclear facilities to international inspection.

The official said that when Russia and Japan attempted to point out some positive elements of the US presentation, the North Korean delegate attacked them by name and said they were lying at the instruction of the United States.

North Korea has insisted for almost a year that Washington and Pyongyang negotiate a non-aggression pact. But the administration has shown no interest. American promises of no hostile intent toward North Korea apparently have not satisfied Pyongyang.

It is widely suspected that US President Bush generated anxiety in Pyongyang by including North Korea, along with Iran and pre-war Iraq, as a member of an "axis of evil" in January 2002.

Also, the White House, in a September 2002 global strategy report, threatened to stop North Korea and other hostile nations before they are able to attack the United States with weapons of mass destruction.

Although there is no clear evidence of a connection, North Korea in the months after the report was issued took a series of steps that caused alarm in Washington, Northeast Asia and beyond.

They included Pyongyang's withdrawal from the Nuclear Non-Proliferation Treaty, cancellation of an eight-year freeze on its plutonium-production program and assertions that reprocessing had begun on spent nuclear fuel rods -- an essential step toward production of nuclear weapons.

The US administration began exerting pressure on North Korea starting last fall after receiving information that the country had launched a uranium-based nuclear weapons program.

The US said North Korea confirmed the existence of such a program to Kelly during a meeting in Pyongyang last fall. On Thursday, however, Kim, according to the US official, said his country has no such program.
