Lebanon's president says his country is eager to take part in Russia-backed political meetings on the Syrian war because it wants to monitor efforts that may accelerate the return of hundreds of thousands of refugees in living in Lebanon.

Michel Aoun says, however, that his country's participation doesn't negate its right to separately work out with Syria ways to regulate the return of Syrian refugees from Lebanon, while others seek lasting political solutions.

Lebanon is host to over 1 million Syrian refugees, the highest per capita concentration in the world.
