According to Censor.NET, Medvedev posted this on his Facebook page threatening to respond to "anti-Russian law" signed by Obama and Ukraine's dismissal of the non-aligned status. "The U.S. president signed an anti-Russian law authorizing the use of sanctions against our country by any U.S. president at any time. As was the case with the Jackson-Vanik law (amendment - ed.), our relationship with the United States will be poisoned for decades," Medvedev said. He further accused Poroshenko of turning Ukraine into a potential military adversary of Russia.
"The president of Ukraine has introduced a bill to the Verkhovna Rada to waive the non-aligned status of the state. In fact it is an application for NATO membership, turning Ukraine into a potential military adversary of Russia. Both of these decisions will have extremely negative consequences. And our country will have to respond to them," the Russian prime minister said.
In March 2014, Russia annexed Crimea. In August 2014, it sent soldiers of the Russian Armed to the east of Ukraine. Over 4,700 people were killed during the conflict in eastern Ukraine, according to the UN.
