Quang Nam Rubber Investment Joint Stock Company, officially operating as Viet Trung Nam Investment and Development Joint Stock Company, is a Vietnam-based diversified industrial and investment enterprise engaged in the manufacturing of cables, cultivation and processing of rubber, commercial trading of agricultural and chemical materials, and real estate infrastructure development. Founded in July 2003 as Viet-Han Corporation and headquartered in the Dien Nam-Dien Ngoc Industrial Park in Dien Ban, Quang Nam Province, Vietnam, the company conducts its business through four core segments: telecommunication and electrical cable manufacturing; rubber cultivation, harvesting, and processing; commercial distribution and trading; and property and infrastructure investment. The company manufactures and supplies a comprehensive portfolio of telecommunications and electrical products under the Viet-Han Cable brand, including copper telephone cables, local area network cables, coaxial cables, and power transmission wires; manages natural rubber plantations and processing facilities producing natural rubber sheets and latex; distributes industrial plastics, plastic pipes, agricultural fertilizers, and specialty chemical products; and provides civil engineering, industrial park infrastructure development, and real estate construction services across Vietnam. In recent major corporate developments, the company executed a strategic restructuring and corporate rebranding, changing its name to Viet Trung Nam Investment and Development Joint Stock Company to reflect its transition into a multi-sector investment group. As part of its latest operational and strategic initiatives on the UPCoM exchange, the enterprise has actively reorganized its capital structure, rationalized non-core assets, expanded its commercial commodity trading network, and redirected long-term investment capital toward regional infrastructure and property development projects in Central Vietnam.
