Truman signed the act into law on May 22, 1947 which granted $400 million in military and economic aid to Turkey and Greece. However, this American aid was in many ways a replacement for British aid which the British were no longer financially in a position to give. The policy of containment and opposition to communists in Greece for example was carried out by the British before 1947 in many of the same ways it was carried out afterward by the Americans.
