In this paper, the emerging international law and China's legal regime for the prevention of invasive species from ballast water are the focus. The international legal regime for ballast water management is first analyzed. Then China's legal framework for ballast water management is assessed. It is questioned whether Chinese law is adequate to combat invasive species from ballast water. China has yet to ratify the 2004 International Convention for the Control and Management of Ships' Ballast Water and Sediments. China's position, its concerns as well as the potential benefits that could result from China's ratification are discussed. Finally, recommendations are provided to better regulate invasive species from ballast water under Chinese law.
