SEOUL, South Korea (AP) - North Korea is vowing to bolster its nuclear force unless the U.S. drops its hostile policy and removes nuclear threats to the communist nation.
Washington denies making any such threats.
After walking away from disarmament talks last year, the North today said its nuclear program can't be traded for economic aid. Pyongyang (pyuhng-yahng) wants sanctions imposed after it quit the negotiations lifted and peace talks formally ending the Korean war before it will return to the bargaining table.
In the meantime, a South Korean news network (YTN) reports North Korea's envoy plans to head to New York to meet with Washington's lead nuclear negotiator sometime in the next few weeks.
A State Department spokesman says he's unaware of any such meetings.
