In 1963, a contract was signed for the Kuraray vinylon plant in Yanshan, Beijing.

After a request from Chinese Premier Zhou Enlai, Kuraray's President Soichiro Ohara agreed to export a manufacturing plant for vinylon—an original chemical fiber developed by Kuraray—to China, and the first large-scale postwar plant export from Japan to China became a reality.
