The potential of market development for marine works is very huge in Latin America, but due to cultural and political system differences, the market is difficult to develop sufficiently. The paper discusses the current situation of the infrastructure in Latin America, and then it summarizes the marketing characteristics of the marine works in this area and gives some advice, in accordance with the experience in practical works. As the economic and trade cooperation develops deeply between Latin America and China, there will be a broader cooperation in the field of marine works between both parties in the future.
