The very same trade deal that former Ukraine President Viktor Yanukovych turned down, sparking violent street battles and his ouster, has been signed by his successor. The deal sets up a free-trade zone for Ukraine as well as for fellow signees Moldova and Georgia. In return, the countries will commit to modeling themselves on EU democracies and improve their human-rights performances. President Petro Poroshenko called it the second-most important moment in Ukraine’s history, after its independence from Russia. “The document we will sign today is not just political and economic, it is a symbol of faith and unbreakable will,” he said.
