US Secretary of State John Kerry and British Foreign Secretary Philip Hammond will co-host talks with 21 countries that are working together to eliminate the Islamic State (ISIS) militants from Syria and Iraq.
Officials from member countries of the US-led coalition will meet in London to discuss the progress and the strategy to tackle the radical group.
The ministers in attendance at the one-day conference scheduled for Friday will also have Iraqi Prime Minister Haider al-Abadi in attendance.
The discussions will also focus on working out a strategy for increasing the humanitarian aid to the two countries and thwarting ISIS' cash flows.
"Terrorists want to drive us apart, but in fact their actions have had the opposite effect - they're bringing us together," Kerry told reporters before the conference.
In addition to Britain, the US and Iraq, other countries to participate in the conference are: Australia, Bahrain, Belgium, Canada, Denmark, Egypt, France, Germany, Italy, Jordan, Kuwait, the Netherlands, Norway, Qatar, Saudi Arabia, Spain, Turkey and the United Arab Emirates.
The US-led coalition meeting is being held for the first time since the radical jihadists carried out the Paris attacks that left 17 dead.
EU foreign policy chief Federica Mogherini stated that the meeting should not be looked on as the West against Islam, AFP reported. He added that the attacks in France "were a little bit like our own 9/11", hitting at "symbols of our culture, of our values, like the media freedom, the police, the Jewish community"
"The meeting tomorrow will be that... of a partnership, a partnership that unites us all against a phenomenon that is brutally devastating societies all over starting with the Arab countries," hr added.
