South East Group is currently trading under the stock number 0726.

Benelux's production facilities are located in Yingde (Guangdong province) and Changzhou (Jiangsu province), where molding and assembly of the core products are performed. The company has partnered with a number of universally known OEM customers in long-term relationships. Additionally, Benelux's production and assembly facilities are contracted to various companies that operates in a efficient and cost effective manner.
