A senior Russian official announced Wednesday that regulations on Moldovan wine imports might be tightened over safety concerns — just days after Chisinau angered Moscow by introducing a “Day of Soviet Occupation." Gennady Onishchenko, head of the Federal Consumer Protection Service, said tighter control might include canceling plans to open new border checkpoints for wine imports. He linked the move to his agency's declaration Tuesday that a check had found that large quantities of Moldovan red wine were substandard. The agency said in a statement that the discovery necessitated “additional measures to tighten control.”
