Iran has behaved irresponsibly in response to international concerns over Tehran's controversial nuclear program, the Russian president said.
The United States and other Western countries suspect Iran of developing nuclear weapons under the guise of a civilian nuclear energy program and are seeking new sanctions following Iran's move to enrich uranium to 20%.
"So far Iran has not shown proper understanding and is behaving irresponsibly... If this situation continues we exclude nothing, including sanctions," Dmitry Medvedev said in an interview with the Danish Broadcasting Corporation (DR) before his official visit to Denmark on Tuesday.
"Sanctions of course are bad in their nature as they seldom yield results. But when all other means of influence are exhausted, we are left with no choice" he said.
The Iran Six (France, Britain, Germany, the United States, Russia and China) began on April 19 discussing the text of a draft resolution imposing sanctions on Iran over its controversial nuclear program.
Russia and China insist on resolving Iran's nuclear issue peacefully, but the United States, Britain, France and Germany are pushing for harsher sanctions against the Islamic Republic.
