The two countries’ presidents met on Friday in Russia’s Black Sea resort of Sochi.

Dmitry Peskov, a spokesman for the Russian president, said Vladimir Putin and Ukrainian President Viktor Yanukovych

discussed “cooperation in energy”, but that “no final agreement” had been reached.

Arseniy Yatsenyuk, a Ukrainian opposition leader allied to the jailed former prime minister Yulia Tymoshenko, had warned that an accord with Russia would be a “political and economic catastrophe”.
