"Our countries are neighbors, and cannot avoid cooperating," Medvedev wrote. "Only now this cooperation will be exclusively, as one might say, 'European,' rational, and pragmatic," he said.
"Building a relationship under new conditions, we leave emotions and 'familial feelings' on the side. Let us not hold back the Ukrainian economy. We do not find this profitable, and frankly it is tiring," the prime minister wrote in the conclusion of his article.
Russian-Ukrainian relations began to sour in 2012 as the latter country pursued an Association Agreement with the EU instead of agreeing to join Russia's proposed Customs Union with Belarus and Kazakhstan. Failure to sign the association agreement in November of 2013 led to the Euromaidan mass protests against former Ukrainian president Viktor Yanukovych, who eventually fled the country in February of this year.
Further complicating relations is the March annexation of the Crimean peninsula by Russia, and alleged support for pro-Russian separatists operating in the south east region of Ukraine.
