Answer:
Belgium received U$524 million through the Marshall Plan directly and through conditional aid.
Explanation:
According to Isabelle Cassiers, during late 1940s and early 1950s Belgium received U$68 million in direct aid from the Marshall Plan and U$446 million through conditional aid.
Conditional aid was a form of compensation to Belgium for its help to other European countries that were its debtors. Belgium got out of the war early, in 1941, so it recovered faster. Because of this by the late 1940s it became creditor of many European nations. The Marshall Plan compensated this economic transation by giving Belgium dollar credits proportionaly to Belgium francs it had lent.
