The Group of Seven's foreign ministers are expected to pledge better use of information, including data on suspects wanted by Interpol, to counter terrorism when they hold talks starting next Sunday in Hiroshima, according to sources.

The ministers will also likely agree on the launch of a new system in which each G-7 country's customs authorities can request airlines' itinerary information on ticketed travelers to limit terrorists' movements, the sources said Sunday.

The two-day meeting will be chaired by Foreign Minister Fumio Kishida, and Japan aims to highlight its contribution to the global fight against terrorism in the wake of the recent deadly attacks in Paris and Brussels.
