From 1981[2] to 1992, American Institute of Physics published a quarterly named Chinese Physics translating selected works selected from 12 physical journals in Chinese including Acta Physica Sinica.

From 1987 to 1989, selected works from Acta Physica Sinica were translated and published as a quarterly under the name of Acta Physica Sinica - Journal of Chinese Physics.

Though once named as the overseas edition of Acta Physica Sinica, it was never an English translation of works on Acta Physica Sinica.
