One out of four American companies put new projects in Russia on hold while more than one-third said they face disadvantages because of U.S. sanctions, the RBC business outlet cited an annual American Chamber of Commerce in Russia survey as saying Thursday.

The sanctions negatively affected the plans of 84 percent of the surveyed companies, RBC said.

Head of AmCham Russia told RBC that business dialogue continues despite “threats of new sanctions on both sides.”

Despite the difficulties, most American companies remain upbeat and expect the strategic Russian market to recover in three years despite a bleak geopolitical outlook, RBC cites Ernst & Young auditor’s managing partner for Russia, Alexander Ivlev.

72 companies including Apple Rus, Coca-Cola HBC Eurasia and ExxonMobil took part in the AmCham Russia survey conducted in April.
