North Korean leader Kim Jong Il's son and the hermit nation's heir apparent, Kim Jong Un, will probably visit China immediately following the National People's Congress in Beijing on March 14, according to a document recently seen by The Japan Times.

The report said Kim Jong Un's visit is timed so he can meet with China's current and next-generation leaders, including Xi Jinping, the presumptive successor to President Hu Jintao.

If this date has to be postponed for some reason, his visit will take place after the April 15 birthday celebrations of North Korea's founding father, Kim Il Sung, and immediately following the visits of high-ranking Chinese officials to Pyongyang, according to the document Kansai University economics professor Lee Young Hwa obtained from a well-informed Chinese source.
