North Korea said on Saturday it is willing to resume six-nation nuclear disarmament talks but would not be hasty because the United States and some other parties were not ready. The statement from a foreign ministry spokesman gave no indication of whether Pyongyang has dropped its preconditions – a lifting of sanctions and separate talks with Washington on a permanent peace treaty.The spokesman was commenting on a visit to China by First Vice- Foreign Minister Kim Kye-Gwan, which ended on Saturday. China, the North's sole major ally and economic lifeline, is pressing to restart the dialogue.Kim, who for years was his country's chief nuclear negotiator, held discussions on the resumption of the talks and the regional situation.
