MOSCOW (Reuters) - Russia may toughen its response to European Union sanctions over the Ukraine crisis if the EU carries out a decision to extend the sanctions, Kremlin economic adviser Andrei Belousov said on Thursday.
He made his comments at the annual St Petersburg International Economic Forum, a day after EU governments agreed to extend the sanctions. Moscow's counter-sanctions include a ban on Western food imports.
Belousov also said there was no consensus yet on a debt restructuring deal for heavily indebted miner Mechel.
