GENEVA Agreements to de-escalate the fighting in Syria could simplify the conflict and lead to a phase of stabilizing the country, but such deals must be an interim measure and avoid partition, U.N. envoy Staffan de Mistura told a news conference on Monday.

Speaking at the start of five days of peace talks in Geneva, de Mistura said discussions were happening in Amman to monitor implementation of a U.S.-Russian brokered ceasefire for southwest Syria, the first peacemaking effort of the war by the U.S. government under President Donald Trump.

“The agreement is basically broadly holding, quite well. In all agreements there is a period of adjustment, we are watching very carefully,” de Mistura said. “But we can say we believe it has fairly good chances of working out.”
