The meeting will discuss progress to date, the essential next steps in the campaign and how the nations of the coalition can accelerate the drive to deal ISIL a lasting defeat, the Pentagon said.
"The Secretary of Defence Ashton Carter will host ministers of defence and other senior leaders from nations of the counter-ISIL coalition and from NATO at Joint Base Andrews, Maryland, on July 20 to discuss the ongoing military campaign against ISIL," the Pentagon said.
"The meeting comes at a significant moment in the counter-ISIL campaign," the Pentagon said.
It follows Carter's visit to Iraq this week, in which he congratulated Iraq forces for recent progress against ISIL forces in Fallujah and Qayyarah and announced the latest support to help accelerate the campaign.
