"I do not think our partners will find is easier to deal with him [Medvedev]. He is a true patriot, and will defend Russia's interests on the international arena very energetically," Putin told journalists after a meeting with German Chancellor Angela Merkel.
Medvedev won just over 70% of the vote in last Sunday's presidential elections. He is to be inaugurated as Russia's new president on May 7.
Medvedev and Merkel, who met in Meiendorf Castle, a presidential staff residence near Moscow, Saturday, said they hoped mutually beneficial bilateral cooperation will continue.
"We highly value your visit to us, and regard it as a continuation of the strategic cooperation and partnership traditionally existing between Russia and Germany," Medvedev said.
Merkel said Russia and Germany "have all prerequisites for successful cooperation."
