Belgian investment company RHJ International has agreed to buy a 20% stake in Japanese supplier U-Shin for JPY8bn ($US68m), according to Reuters.

U-Shin is listed on the Tokyo stock exchange and aims to use the funds to invest in new activities and repay debt, said Reuters.

U-Shin describes itself as a comprehensive manufacturer of electrical components for automobiles, industrial equipment, and the housing industry.

Its products are used in different areas of the vehicle and U-Shin is aiming to increase business by becoming a systems supplier, rather than just a component supplier.
