President Obama says the United States would delay plans to strike Syria - if the country agreed to hand over its chemical weapons.
The government in Syria is accused of using chemical weapons against its own people - but the Syrian President Bashar al-Assad denies this.
Russia suggested on Monday that Syria could give up its chemical weapons.
President Obama said if this were to happen it would put America's plans for military action on hold.
When asked if he would delay plans for a military strike if the Syrian government handed over its chemical weapons, Mr Obama answered: "Absolutely, if in fact that happened."
Syria's civil war has been raging for two and a half years. The UN estimates that 100,000 Syrians have died in the conflict and more than two million have had to flee their homes to neighbouring countries.
