evidence: 50.1°N 168°WThe Sixty-Four Villages East of the River were a group of Manchu, Daur and Han-inhabited villages located on the left (north) bank of the Amur River (Heilong Jiang) opposite of Heihe, and on the east bank of Zeya River opposite of Blagoveshchensk. The area totaled 3600km2. [...] The Republic of China (ROC), has never recognized the Russian occupation as legitimate. In the 1991 Sino-Soviet Border Agreement, the People's Republic of China (PRC) renounced sovereignty of the 64 Villages. However, the Republic of China now based in Taiwan never renounced sovereignty of the area nor does it recognize any border agreements signed by the People's Republic of China with any other countries due to the restrictions imposed by Article 4 of the Constitution of the Republic of China and Section 5 of Article 4 of the Additional Articles of the Constitution of the Republic of China. Therefore, the area still appears as Chinese territory in many maps of China published in Taiwan even though it is now administered as a part of Amur Oblast, Russia.[7]
