President Petro Poroshenko on December 18 submitted to parliament a motion to revoke Ukraine's nonaligned status.
Poroshenko made joining NATO one of his top foreign policy priorities after coming to power in the wake of the Euromaidan revolution in Ukraine, which lead to ouster of Moscow-backed Yanukovych.
The 2010 law, signed by then President Viktor Yanukovych, stipulated that Ukraine wass not to be dependent on other countries or international organizations, was not to join military-political alliances and not to play active part in wars.
He first announced his intention to file the motion during a visit to Warsaw on December 17, RFE/RL reports.
"Ukraine today is in a virtual state of war. Russia annexed Crimea. Illegal armed groups, under the control of our eastern neighbor, are increasing their armed activity in the Donbas"- he said.
