Syria on Sunday rejected an Arab League resolution calling for a joint UN-Arab peacekeeping force in the country and tightened economic sanctions on Damascus, Al Arabiya television reported.
In a brief headline, the channel reported that Syria rejected the Arab decisions "completely". It did not give further details.
Earlier in the day, Arab ministers met in Cairo and adopted a resolution urging the UN to send a new mission to conflict-torn Syria.
The Arab League resolution came a week after Russia and China blocked UN Security Council resolution on Syria.
The Arab League has been at the forefront of regional efforts to end violence in Syria. The group put forward a plan that Assad agreed to in December, and then sent monitors to Syria.
The League withdrew its monitoring mission from Syria in January because the regime failed to the bloodshed.
