"What is going on in Lebanon is pretty much like what is happening in Palestinian-administered territories," Sergei Lavrov told a news conference.
Both Lebanon and the Palestinian Authority are facing a wave of political infighting, which analysts fear may grow into civil wars.
Lebanon's Hezbollah-led opposition has been escalating mass street protests against the government of U.S.-backed anti-Syrian Prime Minister Fouad Siniora. And in Palestinian-controlled territories, supporters of the Hamas-led government have been clashing with allies of the rival Fatah movement and its leader, PA President Mahmoud Abbas.
Russia is deeply concerned over the growing tensions in Lebanon, but it does not aspire to the role of a special mediator in the long-standing conflict between that country and Syria, Lavrov said.
"As for a special mediatory role, I don't think we can aspire to one," said the minister.
He praised the Arab League for its efforts to resolve the political crisis in Lebanon.
