Canada's ambassador to Korea says one major topic of discussion at today's gathering of foreign ministers in Vancouver will be making sanctions against North Korea more effective.
Eric Walsh says several years of many sanctions with varying degrees of implementation have resulted gaps.
He says today's meeting will help identify areas where sanctions are being evaded and look to improve enforcement.
Canada and the U-S are co-hosting the summit, which will bring together ministers from allied countries that sent soldiers to the Korean War in the 1950s.
