KIEV, Dec. 3 – The United States is concerned about Ukraine's intention to revise tariff bindings within the World Trade Organization, as this could undermine the multilateral trading system, U.S, Ambassador Ron Kirk said at a meeting with Ukrainian Foreign Minister Kostiantyn Hryschenko.

"Ambassador Kirk expressed strong U.S. concern about Ukraine's request to alter tariff bindings on more than 350 products that it agreed to when it joined the WTO in 2008," reads the statement.
