This chapter deals with the assessment of transboundary rivers, lakes and groundwaters, as well as selected Ramsar Sites and other wetlands of transboundary importance, which are located in the basins of the Sea of Okhotsk and the Sea of Japan. In the Russian part of the Amur Basin, lakes and reservoirs make up some 0.6% of the area. For most of its length it forms the border between China and the Russian Federation. Mongolia’s share of the basin is comparatively small. The Sungari/ Songhua River, which flows entirely on China's territory, is the biggest tributary of the Amur. River bank protections are being built on the Amur in 2011 in the town Blagoveshchensk.
