Chinese Vice President Hu Jintao will arrive in Moscow on October 27 for a one-day official visit, diplomatic sources told RIA Novosti Friday. The Chinese Vice President is scheduled to meet Russian top officials and to discuss vital international problems and Russian-Chinese relations. The sources don't rule out the counter-terrorism issues will be also discussed. Jintao is to leave Moscow on Sunday, October 28. Observers often call Hu Jintao the most hopeful candidate to the presidential post in the future when the period of Jiang Zemin's constitutional duties is over.
