International talks on North Korea's nuclear programme to firm up a deadline for the country to disable its nuclear bomb-producing facilities have been postponed, officials said on Monday.The talks had been expected to start around the middle of this week, but Japanese and South Korean officials said they would instead meet at a later date that has not yet been set.No reason for the delay was given.The six-nation talks - among China, Japan, Russia, the United States and the two Koreas- have dragged on for years and been beset by delays, but have this year finally made some progress. The North shut down its sole operating nuclear reactor in July and had been displaying willingness to take further steps in exchange for political and economic concessions.Last week, nuclear experts from the US, China and Russia visited the North's nuclear facilities to discuss technical details of disabling them and they reportedly reached an agreement with Pyongyang on how to proceed.On Friday, US Assistant Secretary of State Christopher Hill said in Washington that the talks were expected to begin in the middle of this week.A Japanese Foreign Ministry official said today that host China had informed Japan today that the talks would be postponed.China gave no reason for the postponement and gave no new date for the start of talks, the official said on condition of anonymity due to policy.Another South Korean Foreign Ministry official, also speaking on condition of anonymity, confirmed the talks would not begin Wednesday as had been previously expected.Meanwhile, South Korean presidential spokesman Cheon Ho-seon said that "nothing has been fixed."
