http://uk.reuters.com/article/2011/05/20/uk-korea-north-idUKTRE74J1TX20110520(Reuters) - North Korea's iron ruler Kim Jong-il made a surprise visit to China on Friday, South Korean media reported, amid a series of confusing reports about who was involved and the purpose of the trip.
South Korea's media quoted South Korean presidential and government sources as saying the 69-year-old leader had entered China, the North's only major ally, by train on Friday morning.
Earlier, the same media outlets reported it was youngest son and heir apparent Kim Jong-un who arrived by train in Tumen, in the northeastern Chinese province of Jilin.
A presidential source would not confirm the later reports.
