WASHINGTON/SEOUL (Reuters) - The
United States warned
North Korea on Thursday against any resumption of "unfortunate ill-advised behavior" after
Pyongyang raised international concerns by setting an end-of-year deadline for
Washington to reconsider its diplomatic approach.
Assistant
Secretary of State David Stilwell said that "we have heard threats before," when asked whether Washington was concerned about a return to long-range
missile tests by North Korea, which has vowed to take an unspecified "new path" if the United States is not more flexible in stalled nuclear talks.
North Korea said earlier on Thursday the United States had nothing to offer it in possible renewed talks aimed at getting Pyongyang to give up its nuclear and missile programs, a day after Washington said it was ready to take "concrete steps" toward securing a deal.
