China's President Xi Jinping speaks during his meeting with U.S. President Barack Obama (R), on the sidelines of a nuclear security summit, in The Hague March 24 2014. Obama began crisis talks with his European allies on Monday after Ukraine announced the evacuation of its troops from Crimea, effectively yielding the region to Russian forces which stormed one of Kiev's last bases there. Obama, who has imposed tougher sanctions on Moscow than European leaders over its seizure of the Black Sea peninsula, will seek support for his firm line at a meeting with other leaders of the G7 - a group of industrialised nations that excludes Russia, which joined in 1998 to form the G8.
