Frederick became more concerned over Russian interests when it gained significant influence over Poland in the Repnin Sejm of 1767, a position which also threatened Austria and the Ottoman Turks. In the ensuing Russo-Turkish War (1768–74), Frederick supported Catherine with a subsidy of 300,000 rubles, albeit with reluctance as he did not want Russia to become even stronger through acquisitions of Ottoman territory; this domination of the Ottomans by Russia also concerned Austria heavily. Frederick achieved a rapprochement with the Austrian Emperor Joseph and chancellor Kaunitz, which eased Austrian tension.
