Poroshenko has signed off on the nullification of Russian military agreements:
Ukraine's president has signed into law measures renouncing five bilateral defense-cooperation agreements between Ukraine and Russia.
President Petro Poroshenko signed the measures on June 8 after they were adopted by Ukraine's parliament on May 21, according to a statement on the presidential website.
The nullified agreements include one on the transit across Ukraine of Russian military personnel stationed "in the Republic of Moldova."
Russia maintains troops and peacekeepers in Moldova's breakaway region of Transdniester, although the Moldovan government has repeatedly asked for them to be removed.
The other voided pacts include one on "organizing military interstate transportation," "on mutual protection of secret information," "on military-intelligence cooperation," and "on defense cooperation."
Ukraine has been fighting Russian-backed separatists in the eastern part of the country and claims there are thousands of Russian military personnel operating on Ukrainian territory.
Russia denies that its military is directly involved in the conflict in Ukraine. (Interfax, ITAR-TASS)
