In 2009, the former Minister of Foreign Affairs of the USSR and President of Georgia E.A. Shevardnadze published his memoirs in Russian, which contain an “explosive” plot: while visiting China in February 1989, during his meeting with Deng Xiaoping, a lengthy dispute over border and territorial issues occurred. At that time, Deng allegedly expressed his point of view that vast lands of the Soviet Union, from three to four million square kilometers, belonged to China. Chinese can wait patiently until someday the lands return to China. This content is cited in scientific works by many historians from different countries as an argument. However, there is no other evidence which can prove this recollection. Many details in it contradict the well known historical facts or are completely illogical. There is a good reason to believe that the plot in the memoirs of Shevardnadze is an incorrect recollection. It could even be considered as a made-up story. Moreover, it is possible that it was fabricated for some reasons. Hence, the plot is not worthy of being quoted as a reliable source. At the Sino-Soviet summit Deng Xiaoping did have expressed the point of view that in the past Russia and then the Soviet Union cut off millions of square kilometers of land from China, but at the same time he promised the leader of the Soviet Union that China would not make territorial claims. Since the mid-1980s Deng Xiaoping actively promoted the settlement of the Sino-Soviet border issues through negotiations, which led to the result that 99% of the border between Russia and China was delimited on a legal basis in the last years of his life. At present, the problems of the Sino-Russian border have been finally resolved long ago. There is no doubt that the scientific research and discussions on issues related to territory and borders in the history of Sino-Soviet relations can be made. However, such research and discussions should be based on reliable sources.
