WARSAW, March 12 - Polish meat and meat-product exports to Ukraine are suffering from increased controls by Russia in Ukrainian plants and high Ukrainian duties, Poland's Deputy Prime Minister Andrzej Lepper said.

"The Russian side is searching in Ukrainian as well as in Belarusian meat production plants for meat from Poland [] and on that basis is closing the Russian market for imports of meat and meat products from Ukraine and Belarus," Lepper said Friday.
