The United States said on Tuesday that the refusal by the Democratic People's Republic of Korea (DPRK) to deal with South Korea any more is not conducive to resuming the long-stalled six-party talks.

"Well, that's not going to be conducive to getting us back to the table," State Department spokeswoman Victoria Nuland told reporters.

She insisted on the two criteria that the U.S. has been seeking in getting back to the six-party talks -- the continued improvement of relations between the two Koreas, and "commitment and demonstrated willingness" by the DPRK to come back into compliance with its international obligations and its commitments from 2005.

"So both of those are still on the table from our perspective. So our position certainly hasn't changed," the spokeswoman added.

The DPRK's National Defense Commission said last week that the country would have no dealings any more with South Korea's Lee Myung-bak government, as it prevented the South Korean people from paying condolence visits to late DPRK leader Kim Jong Il, who died of illness on Dec. 17.

Kim had said that his country was ready to resume the six-party talks without preconditions, a mechanism that involves the DPRK, South Korea, the U.S., China, Japan and Russia to denuclearize the Korean Peninsula.

The talks were launched in 2003, but stalled in December 2008, and the DPRK quit the talks in April 2009.

In the 2005 joint statement, seen as the most important result of the six-party talks, the DPRK committed itself to abandoning all nuclear weapons and existing nuclear programs and returning at an early date to the Treaty on the Non-Proliferation of Nuclear Weapons and to the safeguards of the International Atomic Energy Agency.

In the statement, the U.S. affirmed that it has no nuclear weapons on the Korean Peninsula and has no intention to attack or invade the DPRK with nuclear or conventional weapons, while South Korea reaffirmed its commitment not to receive or deploy nuclear weapons in accordance with the 1992 Joint Declaration of the Denuclearization of the Korean Peninsula.
