"We do not accept a role for the United Nations or international forces to monitor the agreement," he told reporters in Damascus.
Russia, Iran and Turkey agreed a deal on Thursday to implement four 'de-escalation zones' in Syria, where regime forces and rebel fighters will cease hostilities.
According to the deal, the areas will be surrounded by "security zones" with checkpoints and observation centres "ensured by the forces of the guarantors by consensus". It also said that "third-party" monitors could be deployed.
