The United Nations Security Council unanimously voted Friday for a plan to secure, and then destroy, Syria's chemical arsenal.
The vote came after weeks of negotiations and the threat of American intervention.
It's seen as a landmark vote because Russia and China vetoed similar efforts in the past.
"We'll have to be vigilant about following through, but this could be a significant victory for the international community and demonstrate how strong diplomacy can allow us to secure our country and pursue a better world," said President Barack Obama.
The Organization for the Prohibition of Chemical Weapons also adopted a plan detailing exactly how the process of compiling and destroying the weapons should take place.
The U.S. contends that a chemical attack in a Damascus suburb in August was carried out by the Syrian government, a charge the Syrian government denies.
An estimated 1,400 people were killed in that attack.
