Yonhap said Mr. Kim’s train left Amur for Ulan Ude later Sunday and his summit with Mr. Medvedev will take place Tuesday at an army base.
The Kremlin press service said that Mr. Kim’s trip, expected to last about a week, would take him into eastern Siberia and that a meeting with Mr. Medvedev would be the main event of his visit. No other details have been released.
Mr. Kim last visited Russia in 2002 on a four-day trip limited to the Far East. A year earlier, however, he made a 24-day train trek across the country to Moscow and back.
