BRUSSELS (Reuters) - Germany is urging the European Union to add up to four more Russian nationals and companies to the bloc's sanctions blacklist over Siemens <SIEGn.DE> gas turbines delivered to Moscow-annexed Crimea, two sources in Brussels said.
The EU has barred its firms from doing business with Crimea since the 2014 annexation from Ukraine, imposed sanctions on Russian individuals and entities, and curbed cooperation with Russia in energy, arms and finance over its role in the crisis in Ukraine.

After it annexed Crimea, Moscow threw its support behind a separatist rebellion in eastern Ukraine, which has killed more than 10,000 people and is still simmering.
The EU's blacklist comprises 150 people and 37 entities subject to an asset freeze and a travel ban. The restrictions are in place until Sept. 15.
"The regular review would normally be the moment to look at who is on the list. In the past, when there were good grounds, we've added entries to the list," an EU official said.
Siemens says it has evidence that all four turbines it delivered for a project in southern Russia had been illegally moved to Crimea.
The proposed additions to the blacklist could include Russian energy ministry officials and the Russian company that moved the turbines to the Black Sea peninsula, one senior diplomatic source said.
Another source said representatives of all 28 EU member states could discuss the matter for the first time in Brussels as soon as Wednesday.
The EU needs unanimity to impose or extend any sanctions.
Hungary, Bulgaria, Italy and Cyprus are among EU states which are usually skeptical of sanctions. They take the line that punitive measures have failed to force a change of course by Moscow but have hurt European business.
Reuters first reported a year ago on the Siemens case, which has exposed the limits of EU sanctions.
Siemens, trying to distance itself from the scandal, last week said it was halting deliveries of power equipment to Russian state-controlled customers and reviewing supply deals.
