MOSCOW (Reuters) - The leaders of Russia, Germany and France have agreed to meet to discuss the situation in Ukraine on Sept. 4-5 in China on the sidelines of the G20 summit, the Kremlin said on Tuesday.

A recent surge in fighting in eastern Ukraine, where Kiev is fighting pro-Russian separatists, and fresh tension in Crimea have raised concern that a fragile ceasefire agreed in Minsk in February 2015 could collapse.
