The ruling by Moscow's Arbitration Court responded to a lawsuit filed by the German engineering firm Siemens against a Russian state firm in July after four turbines which it had sold for use in Russia turned up in the Moscow-annexed region, as reported by Reuters.

The court's report showed it had rejected Siemens' request to take possession of the turbines in an injunction ahead of preliminary court hearings into the dispute set for September 18.

Moscow needs the turbines for two Crimean power plants the Kremlin wants to get running to fulfill a promise, made by President Vladimir Putin, to ensure a stable power supply for the region's residents.

Crimea used to rely on the Ukrainian power grid but is now dependent on Russia for electricity.

The violation of sanctions has prompted the EU to expand penalties against Russia. The new sanctions include Deputy Energy Minister Andrei Cherezov and three Russian companies.

Moscow has said the EU decision to expand sanctions is politically motivated and illegal.
