The move also suggests that China, North Korea's main food and oil supplier, may be seeking an assurance from the isolated state that it drops its nuclear ambitions, one source said, after it ignored warnings from Beijing not to go ahead with a rocket launch in April.
Kim Jong-un's desire to visit China in September was relayed by his powerful uncle, Jang Song-thaek, effectively the second most powerful figure in North Korea, when the latter met Chinese leaders on a visit to Beijing in August.
But China discreetly put off the request, which was never publicized, because the Chinese Communist Party has been busy preparing for its five-yearly congress which is scheduled to open on November 8 when leader-in-waiting Xi Jinping is tipped to replace Hu Jintao as party chief.There is no new timetable for Kim's visit.

Any insistence on Beijing's part for "something positive", for instance that North Korea reins in its nuclear ambitions, would indicate that it is holding its alliance with Pyongyang to a tougher test.
Former North Korean leader Kim Jong-il, who died in December, made six visits to China from 2004 to 2011 while Hu was in office (Hu is president until March 2013), a period that also saw Pyongyang actively engage in missile and nuclear arms development.The Chinese leadership has also had distractions apart from the party congress.
