Lake Xingkai/Khanka is the largest freshwater lake in Northeast Asia, located on the border between the People's Republic of China and the Russian Federation. Its basin is a part of the WusulifUssuri-Heilong/Amur basin. The lake provides a large amount of water resources, and serves as a critical habitat for important animal and plant species, such as red-crowned crane, Grusjaponensis. The project was initiated by the inception meetings in September 1997, where representatives of the two countries visited the lake and had interviewed with relevant experts. Based on the findings at these inception meetings, national reports on the environmental and socio-economic status of the basin have been prepared, and further three reports were prepared by respective focal institutions: (i) general background and water resources in the basin, (ii) biodiversity in the basin, and (iii) socio-economic development of the basin. In December 1999, the final workshop was convened to present the national reports and the three thematic reports. After the final workshop, the Diagnostic Analysis has been compiled based on the three thematic reports. Editing of the national reports and compilation of the Diagnostic Analysis was carried out by Monitor International (U.S.A.).
