Since its construction until 1975, the industrial zone had 94 factories and enterprises. Most of the machinery and equipment were imported from Japan, Germany, France, and Taiwan, among others.
By 1990, Dong Nai Province established the Bien Hoa Industrial Zone Development Company, also known as Sonadezi Bien Hoa, to invest capital, refurbish, upgrade infrastructure, and attract foreign investment.
Until now, many factories and workshops built long ago still exist, featuring old architectural styles.
