After the summit of Tilsit (1807) where Alexander I and Napoleon signed the French-Russian agreements, a fundamental change in Russia's foreign poli-cy in the Eastern Question was produced. The treaty ended the war between the Imperial Russia and the French Empire and spurred an alliance between the two empires that rendered the rest of the continental Europe almost pow-erless. The broad Statement of Alexander I of 14 (26) September 1807, ad-dressed to the Russian ambassador in Paris P. A. Tolstoy, raised for the first time since the beginning of Russo-Turkish War of 1806-1812 some of the trenchant territorial claims of Petersburg. Since 1808 the Russian government considered the annexation of Moldova and Wallachia as a prerequisite (sine qua non) for initiating peace negotiations between Russia and the Ottoman Empires. Russian -French diplomatic correspondence during the period be-tween autumn 1807 and spring 1808 is marked by the controversial and irrec-oncilable dispute pertaining to the evacuation of the Romanian Principalities by Russian troops and Prussian provinces by the French army, an issue skillfully used by Napoleon to achieve his own goals. Following the failure of the Franco-Russian and Russo-Turkish negotiations in Paris, the Russian diplomatic and political circles gradually, but strongly were leaning in favor of direct negotia-tions with the Ottoman Empire. The Napoleon's failure in Spain, and the dan-ger of a war with Austria imposed French diplomacy to be more conciliatory towards Russia. Russian diplomacy in the new situation aimed primarily to ob-tain from France a waiver from mediation and the official recognition of Ro-manian Principalities' incorporation in the composition of Imperial Russia.
