BERLIN, July 21. /ITAR-TASS/. Almost a quarter of German export companies is affected by sanctions imposed by the United States and the European Union on Russia over the Ukraine crises, the German Chambers of Industry and Commerce (DIHK) said on Monday.

“That concerns about every fourth German company active abroad,” DIHK foreign trade expert Volker Treier told the German daily newspaper Rheinische Post.

The discrepancy between the US and EU sanctions posed an additional challenge for German firms active in Russia and the United States, the expert said. The incompatible sanctions forced export companies to revise almost every aspect of their commercial activities, he said.
