The implementation schemes for the action plans of environmental protection are made on EIA of Naii Navigation Complex of Youjiang River Navigation Construction of Guangxi., one of the projects with aid of World Bank loans. On this basis, the plans for project management, monitoring implementation and personnel training are made. In consideration of the environmental activities for Naji Navigation Complex as well as the characteristics and regional environment of the project, The following principle shall be followed: to focus on prevention, make comprehensive prevention and treatment, enforce control scheme and management and gradually eliminate the environmental pollution caused by the activities of project construction. Moreover, the regional environment in connection witlh the project construction can be well protected. The first draft of The Action Plan was submitted to the World Bank in July 2002 and the first revision based oni the first draft was completed on 31 St January, 2003. This Action Plan was revised and completed in the light of the World Bank's commernts to the first draft and with reference to the environmental protection action plans of other projects supported by the World Bank loans.
