This paper examines the connection between China's domestic governance and its involvement in global governance in environmental protection by studying the major actors and issues involved in the interaction between the domestic and international spheres of activities. These actors include international institutions, national and local governments, nongovernmental organisations, and others. The paper demonstrates that China has made some substantive progress in protecting its environment, but much more needs to be done. Internationally it seems to lack the will or the capability to make much contribution towards global environmental governance. However, because of its huge aggregate size, what it does or does not do to avert environmental degradation at home could have a significant impact on collective efforts to protect the environment at the global level.
