MOSCOW, Feb. 24 - Russian consumer rights watchdog Rospotrebnadzor said the list of Ukrainian companies whose cheese will not be allowed into Russia could be expanded.

"By all accounts, the list of cheese suppliers to the Russian market will be expanded," Rospotrebnadzor chief Gennady Onishchenko told Interfax on Friday.

Ukraine is in no hurry to resolve the cheese problem, he said.

"What is going on in our relations can be described as simulation of activity, not real willingness to find an early solution to the problem," Onishchenko said.
