The European Union on Friday (4 August) imposed sanctions on three more Russians, including Deputy Energy Minister Andrei Cherezov, and three Russian companies over the delivery of Siemens’ turbines to Moscow-annexed Crimea.

The EU first introduced sanctions on Russia after the 2014 military takeover of the Black Sea peninsula from Kiev, and stepped them up repeatedly as Moscow then backed separatist unrest in the east of Ukraine.

The latest tightening comes in response to the delivery of Siemens’ gas turbines to Crimea in violation of EU sanctions, which bar doing business there since the annexation that has not been internationally recognised.

Siemens says it has evidence that all four turbines it delivered for a project in southern Russia had been illegally moved to Crimea.

The EU said the blacklisted companies include Siemens’ two Russian contractors that moved the turbines.

Siemens turbines cause whirlwinds in Crimea A firm part-owned by German firm Siemens was preparing to install electricity turbines in Crimea despite prohibitive EU sanctions. The issue was brought to the attention of Brussels and Siemens on Monday (10 July).

EU’s 28 states must be unanimous to go ahead with sanctions and diplomatic sources said Italy’s opposition meant a fourth name had to be dropped from the initial German proposal.

Diplomats in Brussels said the Russian energy ministry official is involved in bilateral cooperation with Italy and has since escaped being sanctioned. The Italian representation in Brussels did not immediately respond to a request for comment.

Other EU sanctions on Russia target its energy, financial and arms sectors. The latest additions complement a blacklist that already contains 150 people and 37 entities subject to an asset freeze and a travel ban over the turmoil in Ukraine.

More than three years of coordinated EU and U.S. sanctions, however, have not forced a change of hand in Moscow, which vows to never give back Crimea and still supports the armed conflict in east Ukraine which has killed more than 10,000 people.
