Many Russians know that most Chinese know that in the 1860s, tsarist Russia acquired 1.4 million square kilometres of Chinese territory.
In a world of growing complexity and uncertainty, the Russo-Chinese relationship is not sufficiently robust to serve as a stabilising force.
Russian cooperation which builds Chinese military capabilities is more important and more detrimental to Western interests than any grand rhetoric coming out of officials’ mouths.
Russia’s adaptation to the asymmetry in relations with China stands in stark contrast to its clash with the EU over Ukraine and Eastern Europe in general.
Western interests and norms are challenged less by the Sino-Russian partnership than by China and Russia acting individually.
As long as China doesn't challenge the fundamental system of rule in Russia (as the US does), then it will remain a preferred partner if not an ally.
