The Syrian government has written to Kofi Annan to accept his six-point plan, endorsed by the United Nations Security Council.
"Mr Annan views this as an important initial step that could bring an end to the violence and the bloodshed," said a spokesman for the joint special envoy.
Mr Annan has stressed that implementation will be key, not only for the Syrian people, who are caught in the middle of this tragedy, but also for the region and the international community as a whole. As the Syrian government acts on its commitments, Mr Annan will move urgently to work with all parties to secure implementation of the plan at all levels.
Syria has accepted his plan to end the country's bloodshed but diplomats say they will wait for actions not words from the Assad regime.
