Syrian Foreign Minister Walid Muallem has invited the "nationalistic opposition" to lay down its weapons and join talks to form a new government.
Muallem said any opposition group could join a new cabinet as long as they reject foreign intervention, reports the BBC.
He also said any discussion of President Bashar al-Assad's future was "unacceptable".
Muallem said that despite the continued bloodshed, the current government would continue to lay the groundwork for dialogue and transition over the next three months.
Muallem reiterated the embattled leader's position that a new parliament and constitution were the only way forward out of the conflict.
He was speaking on Syrian state television a week after United Nations and Arab League envoy Lakhdar Brahimi said the president should not be part of a transitional government.
He called for the UN to intervene to help secure Syria's borders - although the Syrian government would have to agree how this would be achieved. (ANI)
