Syria’s military has launched fresh airstrikes on rebel compounds in the capital, Damascus.
The planes carried out raids on Thursday, pummelling areas east of the city, where clashes have raged for months.
The number of dead or injured was not immediately available.
Divisions over how to end the 19-month conflict remain.
Western powers have been pushing for UN sanctions against Syria, but they have been vetoed by China and Russia.
Now Beijing has presented a new proposal for a truce between the Assad regime and the rebels.
“The specific constructive suggestions in the proposal such as a phase-by-phase and region-by-region ceasefire and the establishing of a transitional governing body, are made by China based on the latest situation, Annan’s six-point plan,” said Chinese foreign affairs spokesman Hong Hei.
At least six people died late last night when a device exploded at a Shiite shine in Damascus. 13 people were injured.
Syrian state television blamed the attack on what it called “foreign-backed terrorists.”
More than 30,000 people have been killed since the uprising against President Bashar Assad began over a year and a half ago.
