Of the five Korean car manufacturers - Hyundai, Ssangyong, Daewoo, Samsung and the troubled Kia Motors - Daewoo has emerged as the most prolific.
Expansion has occurred for all the companies concerned, except Kia which is fighting to stave off bankruptcy.
Daewoo is now manufacturing in a number of countries, most notably in eastern Europe, while Samsung, the newest entrant to the highly competitive Korean domestic market, is expected to begin exports to Asia next year.
Samsung's Nissan-based models are expected to start rolling off the production line in March next year.
The new plant at Pusan will produce 80,000 cars next year, rising to 200,000 units by the end of the decade.
Daewoo has bought a controlling interest in Polish vehicle manufacturer FSO and is also starting production in Romania.
In addition, an engine-building facility is expected to be established in Britain, along with a car production factory.
