Turkish Foreign Minister Ahmet Davutoglu has said that the international community would not allow Syrian President Bashar al-Assad to "misuse another opportunity." He said the current efforts to end the conflict there represented a final chance for the regime.
Davutoglu told a news conference that the international community had been too slow in responding to the Bosnian conflict in the 1990s and it should now act decisively and without delay.
A communique expected from the Friends of Syria in Istanbul is expected to give full support to U.N.-Arab League envoy Kofi Annan's peace mission while stressing that it cannot be open-ended.
The communique would also recognise the legitimacy of steps taken by the Syrian people to defend themselves.
Conference sources have said Gulf Arab states were ready to funnel millions of dollars through the opposition Syrian National Council to pay recruits who defect from Assad's forces to join the rebel Free Syrian Army.
Britain has announced a doubling of non-lethal help for the Syrian resistance, a tactic already adopted by the US and one that Turkey has said it will match. Some Gulf Arab nations said more backing should be given to the Syrian Free Army to protect civilians from Assad's crackdown on the revolt.
Hague said that participants in the Istanbul meeting were discussing what form financing for the opposition should take, adding it was undecided whether it would be a "trust fund", as suggested by some governments.
The British minister noted the efforts by the opposition Syrian National Council to become a more open and inclusive group, saying it had "done better in recent days".
The Assad regime has said they accepted the Annan plan but they haven't done anything about it. The fighting continues.
Increased financial support for the opposition will be one of the consequences of the Assad regime playing for time in implementing the Annan proposals.
One of the messages from this (Friends of Syria) conference is that it will be important to implement the Annan plan, and there isn't an indefinite amount of time to do that before we here, the Friends of Syria, need to go back to the United Nations Security Council or intensify funding for the Syrian opposition.
We do need the Assad regime to take action not just words. That does not mean that today we will set an expiry date, but it does depend what they do on the ground.
