Mr Howard told parliament the meeting would discuss issues surrounding the AWB’s wheat export monopoly.
"Our primary concern is of course the interests of the Australian wheat growers," Mr Howard said.
It follows a decision by the Iraq Grains Board to suspend all contact with AWB, blocking it from a current tender worth almost A$300 million, until completion of the Cole inquiry.
The Cole inquiry is examining claims of kickback payments made by AWB to Saddam Hussein’s regime, allegedly in breach of the United Nation's oil-for-food program.
Mr Howard said the issue of the decision by the Iraq Grains Board and its current tender process was separate to the overall issue of Australia's wheat monopoly selling system.
"That is an issue which has attracted debate on both sides of the argument, and let me say it remains the government's policy to support the existing provisions," he said.
"And there would need to be a strong national interest case in order to alter that.”
There have been calls from within government ranks for changes to be made to the way Australia exports its wheat for some time.
Treasurer Peter Costello has indicated in the past he supports change.
The government is due to review the system by 2010.
