According to the Dong-A Ilbo , Russia has built a wall beside the Duman river which forms the border between itself and North Korea.

Russia started a project to “stabilize the river bed of the Duman River and to reinforce defenses on the border between Russia and North Korea” in November 2004. It completed a bank revetment 12.995 km-long along the riverbank in July last year. Now it has strengthened it along a 9.45 km stretch where the bank had been eroded by water.

Could it be that Russia is quietly preparing to stem a huge flow of refugees given that North Korea is on the verge of collapse?

This follows China’s decision to put up a 20Km fence along their border.

Also in the same article is a reference to what could be the next territorial dispute for Korea.

Meanwhile, some say that the return of Nokdun Island, which belonged to Joseon until the 19th Century would become more difficult due to the bank revetment. International law experts explained that if Russia builds a dike around Nokdun Island, it would provide more evidence of practical possession, and their claim to the island would be stronger.

Nokdun Island is four times bigger than Yeouido and is located in the river mouth of Duman. Nokdun Island was claimed by Russia when North Korea signed its border treaty. However, it had been Joseon territory from King Sejong’s reign through 1860 when a Beijing treaty was made. Many records support this fact, including some documents proving that General Yi Sun-shin stayed on the island for three years and that Joseon farmers cultivated this island into farmland and set up a palisade.

When Imperial Russia obtained the Maritime Province from China according to a Beijing treaty, it claimed Nokdun Island as its territory over the transom. Nokdun Island has been connected with the Russian side after sand in the upper stream of the Duman River came down and accumulated after the 1800s. Russia’s military units are located on this island at present.

This could be something that will rear its head again in the future.
