The United Nations announced Monday that Secretary General Ban Ki-moon would convene peace talks in Geneva on Jan. 22, 2014, bringing both sides to the table.
The conference's goal is "the establishment, based on mutual consent, of a transitional governing body with full executive powers, including over military and security entities," the UN said in a statement.
Ban said it would be "unforgivable not to seize this opportunity to bring an end to the suffering and destruction."
"The war continues to send tremors across the region," Ban said Monday, adding that it forced "unacceptable burdens" on Syria's neighbors.
The latest attempt at a peace conference comes after the UN, US and Russia have tried (and failed) to get the opposing sides to the negotiating table to find a political solution.
Previous attempts at bringing Assad and the Syrian opposition to the table have failed due to disputes over who would represent each side, and demands set by each side.
