Deputy Foreign Minister Alexander Panov said Pyongyang, defiant in the face of possible sanctions, might be more flexible in multilateral talks.
"We do not say attempts by the UN Security Council should be stopped," Panov told a news conference.
"But what we see is that its previous attempts have had no result," he said. "We think the time has come for multilateral consultations."
The crisis erupted earlier this month after the Vienna-based International Atomic Energy Agency said experts sent to inspect North Korea's seven declared nuclear facilities were not permitted to carry out full investigations.
The United States drafted a resolution last week urging North Korea to allow the IAEA to complete the probe.
The document, which called for further action if needed, could be a step toward sanctions .
South Korea President Kim Young-sam took a conciliatory line Tuesday and a leading Northern diplomat said his side would not be the first to fight.
"Through consultation and dialogue I believe we can solve this problem smoothly," Kim said at a news conference near the end of a trip to China.
A senior North Korean ambassador answered with an emphatic "no" Tuesday when asked about the possibility of the North attacking the South.
"We are defensive only," ambassador to Thailand Li Do Sop said during a news conference in Bangkok."We have built many things. We don't want to destroy anything," he said.
Moscow last week suggested both Koreas, China, Japan, the United States and Russia should hold a conference to solve the crisis. Panov said Pyongyang had not rejected Russia's proposal.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."

We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
