Pyongyang, October 20 (KCNA) -- The World Food Program (WFP) said concern about food supply is increasing in the whole world, particularly in developing countries.

In a report released recently WFP predicted that the food price hike will continue beyond calculation in the future.

The report said the state of emergency caused by the food price hike and unfavorable weather condition makes it more difficult to solve the food problem.

People in developing nations spend 80 percent of their incomes for purchasing food, it added.
