State Department spokesman Sean McCormack said: "We told the Belarusians in private, and we will say in public, that we believe that this action is unjustified and unwarranted".
"Since this was a formal diplomatic request, we will comply with it," McCormack said, adding that the United States is considering its response.
It appears the moves are in retaliation against Washington's new sanctions on Belarus' national oil products firm Belneftekhim last year.
