After a year of negotiations, the Treaty of Paris was signed on 18 April 1951 establishing the European Coal and Steel Community. The treaty was unpopular in Germany where it was seen as a French attempt to take over German industry. The treaty conditions were favorable to the French, but for Adenauer, the only thing that mattered was European integration. Adenauer was keen to see Britain join the European Coal and Steel Community as he believed the more free-market British would counterbalance the influence of the more "dirigiste" French, and to achieve that purpose he visited London in November 1951 to meet with Prime Minister Winston Churchill. Churchill said Britain would not join the European Coal and Steel Community because doing so would mean sacrificing relations with the U.S and Commonwealth.
