Since Malaysia opened its doors to foreign investment in 1986 with its improved infrastructure, it has successfully attracted a large number of foreign investment to set up companies, investments, and manufacturing industries in Malaysia. Setting up a company in Malaysia used to rely on the commodity economy such as rubber and tin, transforming and developing the manufacturing and technology industries. In recent years, it has gradually paid attention to the development of the service industry. In terms of foreign investment by country, Japan is the largest foreign investor in Malaysia, followed by the United States and Singapore, and Taiwanese businessmen rank fourth in foreign investment in Malaysia.
