Sino-Russian relations both present and past are a most absorbing object of study for specialists and laypeople alike, for seldom in human history can two countries so different have become neighbours. Moreover, the importance of these relations today for world politics and for all our futures is so immense that everyone should be informed about them to some degree. Present events cannot be well understood without a knowledge of the background from which they sprang, yet a short introductory history of Sino-Russian relations has until now not been available. It is to meet this need that the present book has been written.
