Vina-Mazda is developing many showrooms throughout the country, including Bien Hoa city of Dong Nai province, Danang, Hanoi and HCMC. Vina-Mazda has imported completely built-up (CBU) Mazda cars including Mazda 2, Mazda 3, Mazda 6 and Mazda CX9 for the local market. In the past the Mazda cars were assembled in the country through local automaker VMC but the production was later suspended. This is the second automobile venture in the Chu Lai Open Economic Zone after Truong Hai Auto Joint Stock Co., better known as Thaco, which has a huge auto manufacturing and assembly complex. In 2007 Thaco Kia opened a S$36 million factory to assemble passenger cars. This firm started production and assembly of Hyundai commercial vehicles in May this year.
