Sunwah has invested in Cambodia for more than 25 years. In the early years, it focused primarily on the import and export trade. Its business extends to manufacturing and processing of seafood for export. Subsequently Sunwah is now a renowned real estate developer with portfolios in Cambodia.
In 1995, Sunwah established a Cambodia headquarters in Phnom Penh, and built a large scale 10-hectare seafood processing plant at the Sihanoukville Port with a total investment of US$10 million. This was one of the largest seafood processing plants in Cambodia for export of frozen seafood products to Hong Kong and worldwide.
