The Ukrainian parliament has voted to annul military cooperation with Russia.
The five intergovernmental agreements scrapped by the Verkhovna Rada on May 21 include one allowing Moscow to send forces across Ukraine to Moldova's breakaway Transdniester region.
The lawmakers also voted to terminate deals covering military intelligence cooperation and the mutual protection of classified information, basic Russian military transports across Ukrainian territory, and mutual arms purchases.
The move comes as eastern Ukraine continues to be embroiled in sporadic fighting between government forces and pro-Russian separatists despite a cease-fire agreement signed in Minsk in February.
More than 6,100 people have been killed in the conflict since April 2014.
Kyiv and the West accuse Russia of arming the rebels and sending troops there, charges Moscow denies.
