In this Paper, we discuss the impact of new development of port of Ho Chi Minh, Viet Nam on maritime contai ner cargo transport market with the equilibrium approach. We assume three types of vessels can be handled in the market; 1000, 3000 and 6000TEU vessels. The results say that the port of Ho Chi Minh can deal the transshipped cargo from Hyphon to Hong Kong a/o Singapore with main use of 3000TEU vessels. We conclude that the status of the port of Ho Chi Minh heavily depends on the neighboring big gateway ports, Hong Kong and Singapoe.
