 The territory transfer would connect a previously enclaved piece of Chinese territory to the rest of China (Fangchuancun).This portion of the agreement stirred up some controversy among some Russian officials from Primorsky Krai, as they felt that direct Chinese access to the Sea of Japan (through the Tumen River) would decrease the economic importance of Vladivostok and Nakhodka.Other arguments protested at potential pollution from Chinese economic development, the possibility of Chinese military vessels navigating the river, and the presence of a Russian cemetery commemorating the Lake Khasan Incident in the area.
