Austria-Hungary's thoughts on Russia

During the time of the French Revolution and the Congress of Vienna, Austria was distraught over Russia's influence in Poland (Grand Duchy), Central Europe, and Prussia. During the debates in the C.O.V., Russia was Austria's main rival in negoatiations. Russia's strength seemed to grow over the years and the balance of power was tipping gradually in their general direction. Austria-Hungary felt weak in comparison. Furthermore, Russia had somewhat of an influence over King Frederick William III, king of Prussia. Prussia was somewhat of a buffer state between Austria-Hungary and Russia.
