Prominent Ukrainians urge US, EU to speak with one voice against Russia

Two potential Ukrainian presidential contenders are urging the U.S. and European Union to stick to a single, tough stance against Russia.

While Washington is imposing sanctions and strongly criticizing Moscow, the EU has taken softer measures. Some European countries are wary of antagonizing Russia, a major energy supplier and trade partner, and anything that might lead to war.

Ukrainian magnate Petro Poroshenko told reporters in Paris on Friday that Ukraine wants the EU and U.S. "to speak in one voice and be on the same wavelength."

Former boxer Vitali Klitschko, a leader of the protest movement that sent Ukraine's president fleeing last month, said "we need a joint position by all EU countries and the United States."

Both men sought support for Ukraine at meetings with European leaders Friday.
