UPDATE 1-French, German ministers to travel to Ukraine for talks

(Adds details from German and Ukrainian foreign affairs ministers)

PARIS, Jan 29 (Reuters) - France and Germany's foreign affairs ministers will travel to Kiev for talks with their Ukrainian counterpart Dmytro Kuleba on Feb. 7-8, they said on Twitter.

German Foreign Affairs Minister Annalena Baerbock said the visit aimed to reinforce Germany's solidarity with Ukraine.

French Foreign Affairs Minister Jean-Yves Le Drian said he had talked with Kuleba and assured him that France was fully mobilised to find ways to de-escalate the crisis in Ukraine.

The United States and other western allies of Ukraine fear that Russia could be preparing to invade Ukraine as it has amassed more than 100,000 troops near its borders. Russia denies it is planning any invasion.

Baerbock said she was working to defuse the situation under the so-called Normandy format that includes Germany, France, Russia and Ukraine.

The four-way Normandy format talks -- set up after Russia annexed the Crimean peninsula from Ukraine in 2014 -- are aimed at helping end a long-running conflict in eastern Ukraine between government forces and pro-Russian separatists.
