Harbin, the capital of the Chinese Eastern Railway, a unique Russian city in China, which sheltered hundreds of thousands of refugees from Russia devastated by the Civil War, for a quarter of a century turned into the arena of a fierce battle between the intelligence services of the leading world powers.
