Germany has paid back all of its reparations:
"After World War II, according to the Potsdam conference held between July 17 and August 2, 1945, Germany was to pay the Allies US$23 billion mainly in machinery and manufacturing plants. Reparations to the Soviet Union stopped in 1953. Large numbers of factories were dismantled or destroyed.[citation needed] Dismantling in the west stopped in 1950.Beginning before the German surrender and continuing for the next two years, the United States pursued a vigorous program of harvesting all technological and scientific know-how as well as all patents and many leading scientists in Germany (known as Operation Paperclip). Historian John Gimbel, in his book Science Technology and Reparations: Exploitation and Plunder in Postwar Germany, states that the "intellectual reparations" taken by the U.S. and the UK amounted to close to $10 billion.[8] German reparations were partly to be in the form of forced labor. By 1947, approximately 4,000,000 German POWs and civilians were used as forced labor (under various headings, such as "reparations labor" or "enforce

On January 14th 1946, in Paris, two forms of reparation were set up for the allies, in forms of shares: all reparations including funds, and those in the form of 'industrial and other capital equipment'. The U.K., U.S., France and Yugoslavia were the biggest shareholders.
