ROME?Led by Cuba, developing countries on Tuesday demanded greater access to international markets and an end to export subsidies, saying fairer free trade is the only way to end world hunger.

On the second day of the U.N. World Food Summit, leaders of the world’s poorest countries called on the United States, European Union and other exporting nations to give poor farmers a competing chance to sell their wares.

Many poor countries say the current international trade framework leaves farmers in the developing world unable to compete with subsidized crops from richer countries.

The issue of freer markets has dominated the four-day summit, designed to accelerate efforts to meet U.N. targets of reducing the number of the world’s hungry from 800 million to 400 million by 2015. Leaders adopted a resolution Monday promising to work harder to meet the goal.
