But raising money for humanitarian aid in North Korea has become more challenging as Pyongyang has poured resources into its nuclear and missile programmes rather than feeding its people, and been hit with multiple rounds of UN sanctions as a result.
"We still need greater access, more information, more data," he told a press conference in Seoul.
"I said very clearly... you have people around the world that are concerned that the food and the money won't go to its intended consequences." Around the world, the number of "severely hungry" people had spiked from 80 million to 124 million in the last three years, he said, while the WFP was two to three billion dollars short of its funding goals.
But the WFP chief said he felt "a tremendous sense of optimism" in his meetings with North Korean officials in the hopes of "turning a new chapter in history".
Dialogue brokered by Seoul has seen US-North Korea relations go from trading personal insults and threats of war last year to a summit between Kim and President Donald Trump due in Singapore on June 12.
Experts say that North Korea needs to produce around 6.5 to 6.7 million tonnes of food to feed its population, but usually grows around one million tonnes less than that, leading to chronic shortfalls.
According to the UN Food and Agriculture Organization's 2017 report on global food security and nutrition, 10.3 million North Koreans are now considered to be undernourished -- around 41 percent of the population.
Sanctions imposed on Pyongyang over its weapons ambitions "slows down the time to get items such as food in because some companies obviously are very concerned about being blacklisted", Beasley said.
