(ANSA-AFP) - KYIV, 03 DIC - Ukraine's presidency on Saturday said a $60 price cap on Russian oil agreed by the EU, G7 and Australia "will destroy" Russia's economy. "We always achieve our goal and Russia's economy will be destroyed, and it will pay and be responsible for all its crimes," Ukraine's presidential chief of staff Andriy Yermak said on Telegram. But a cap of "$30 would have destroyed it more quickly", he added. (ANSA-AFP).
