Brown also said he hoped the upcoming summit would produce a plan to boost food production worldwide and bring down prices for consumers.
"We need to expand aid and help we give for agricultural production," he added.
Brown also welcomed other issues confirmed as summit topics by Fukuda, including the global economy, climate change and development.
For his part, Fukuda said rising food prices were an "urgent international issue," and were "a multifaceted problem that calls for a multifaceted response."
