French President Francois Hollande and German Chancellor Angela Merkel are in Moscow for talks with President Vladimir Putin on Ukraine.
They've traveled to Russia after discussions in Ukraine's capital Kiev centred around a new peace plan.
The new round of diplomacy comes amid intensified fighting in eastern Ukraine.
The US is also considering supplying defensive weapons to Kiev to fight rebels in the east.
Russia denies claims it is arming pro-Russian separatists, or that it has troops fighting alongside rebels in the Donetsk and Luhansk regions.
