South Korean officials said the talks have been extended to continue on February 13.
Diplomats say they are waiting for a response from North Korea to offers of energy aid in exchange for the North abandoning its nuclear weapons.
"It is up to the North Koreans," said U.S. Assistant Secretary of State Christopher Hill, the chief U.S. negotiator at the talks. "I think we have put everything on the table. We have really, I think, offered a way forward on a number of issues. They just need to make a decision. I don't think there is any need to do any more bargaining. I just think they need to make a decision."
Reports say North Korea's earlier demands for massive amounts of energy aid have been rejected.
The United States has said today could be the last day of the current round of talks.
The six-party talks involve North Korea, China, South Korea, the United States, Russia, and Japan.
