German Foreign Minister Guido Westerwelle slammed Thursday as "simply unacceptable" economic and political pressure on Ukraine, in a thinly veiled jab at Kiev's Soviet-era master Russia. "The threats and the use of economic pressure which we have seen over the last year are simply unacceptable," Germany's outgoing foreign minister told an OSCE security meeting in the Ukrainian capital Kiev. "The people in Ukraine want to decide their future themselves," he said, noting he was "worried" by a police crackdown on protesters.
