Payments of reparations started in 1955, lasted for 23 years and ended in 1977. For countries that renounced any reparations from Japan, it agreed to pay indemnity and/or grants in accordance with bilateral agreements. In the Joint Communiqué of the Government of Japan and the Government of the Peoples Republic of China (1972), Peoples Republic of China renounces its demand for war reparation from Japan. In the Soviet-Japanese Joint Declaration of 1956, the Soviet Union waived its rights to reparations from Japan, and both Japan and the Soviet Union waived all reparations claims arising from war. Additionally, Ceylon (now Sri Lanka), under President J. R. Jayewardene, declined war reparations from Japan.
