"It is hard to make any country, be it Syria or any other country in the world, disarm unilaterally if some forcible action is being prepared against it," Putin said, according to Interfax.
The Russian president said Syria's chemical weapon stocks were a proliferation threat. Putin also suggested this may take a bit more time, saying: "We also believe that this is a serious matter that requires an additional and serious consideration."
"We will work together with the Syrians and with our American partners," he said.
Obama and Putin discussed the proposal when they met on the sidelines of the G-20 Summit Friday, according to the Kremlin.
Obama told ABC News anchor Diane Sawyer Monday that if Syria were to turn over its chemical weapons, it would "absolutely" halt his plans to strike inside Syria.
Obama is scheduled to address the nation tonight to make his case to a skeptical nation about his plans to strike Syria in response to an alleged chemical weapons attack outside Damascus Aug. 21. The United States says it has evidence that Syrian was behind the attack.
In light of the Russian proposal, the White House is reportedly changing what Obama plans to say in his address.
