There will be a particular focus on the jihadist Islamic State group.
The December 17 meeting at the United Nations in New York is expected to adopt a resolution designed to choke off terror groups' sources of finance, the Treasury said in a statement yesterday.
It will be the first such meeting of finance ministers specifically from Security Council member nations, the Treasury said, calling it a demonstration of "the increasingly specialised work needed to combat terrorism."
"A united international front is vital to achieve that goal."
The Treasury has undertaken extensive efforts since the terror attacks of 2001 to trace and combat the financing of violent extremist groups around the globe.
