To whom did Ms. Tonaka tell about her idea?

Japanese Foreign Minister Makiko Tanaka is reported to have voiced concerns over Washington’s plan for a missile defense system.
    Japanese news reports Friday said Ms. Tanaka told Italian Foreign Minister Lamberto Dini in Beijing last Friday that she was concerned about U.S. plans to deploy missile defenses.
    The reports said she also suggested that Japan and Europe must cooperate in urging Washington to show caution about the plan.
    If the remarks are confirmed, it would put Ms. Tanaka at odds with Tokyo’s official position that it "under-stands" Washington’s plan to develop the National Missile Defense project.
     Washington says the system is needed to protect the United States and its allies from attack by so-called rogue nations.
