Libya, which holds the rotating presidency of the Arab leaders' summit, said this week that the Baghdad meeting would be postponed because of the situation in the region, where protests are challenging leaders from Bahrain to Algeria.
The presidents of Egypt and Tunisia have been toppled by mass protests this year.
A statement issued from the Arab League headquarters in Cairo said a formal request for the postponement of the summit had yet to be received by the body's general secretariat.
The summit is set for March 29.
"The general secretariat stresses the importance of the holding of the coming Arab summit on schedule," the League statement said.
Current circumstances required "the greatest degree of coordination and discussion to deal with the grave, fateful developments which the Arab region is going through," it said.
