evidence: As the Republic of China, now based in Taiwan, has never recognized the People's Republic of China nor its border treaties with other countries, some maps published in Taiwan still show the entire Heixiazi Island and the Sixty-Four Villages East of the River as Chinese territories. However, these maps show Outer Manchuria, sometimes called "lost territories in the Northeast" (東北失地), to be Russian territory. Some Manchu and Han Chinese regard Outer Manchuria as territory that was unfairly taken away, as in Mao's comments leading up to the Sino–Soviet border conflict.
