万国著作権条約
The United States and most Latin American countries instead entered into the Buenos Aires Convention in 1910, which required a copyright notice on the work (such as "all rights reserved"), and permitted signatory nations to limit the duration of copyrights to shorter and renewable terms. The Universal Copyright Convention was drafted in 1952 as another less demanding alternative to the Berne Convention, and ratified by nations such as the Soviet Union and developing nations.
