Ukraine's parliament has voted to drop the country's non-aligned status and work towards Nato membership.
Russian Foreign Minister Sergei Lavrov called the move "counterproductive" and said it would boost tensions.
Ukrainian President Petro Poroshenko pledged to seek Nato membership over Russian support for rebels in the east.
