Buenos Aires, Jul 22 (IANS): Argentine President Alberto Fernandez has called for strengthening the Southern Common Market (Mercosur), which he said is capable of supplying food to the entire world.

"We have before us a formidable and unique opportunity to come to the aid of the hungry in the world if we know how to agree to take advantage of it," he added on Thursday.

The President was addressing the plenary session of the LX Summit of Heads of State of Mercosur and Associated States in the Paraguayan city of Luque, according to a presidency press release.

Fernandez urged the bloc of Argentina, Brazil, Paraguay and Uruguay, to "walk together" during the current challenging global situation because "united we are stronger," Xinhua news agency reported.

"We have the moral imperative to agree to produce the food that the rest of the world needs. We should all want a fairer, more balanced and egalitarian continent that interacts differently ... because the world that is coming is a world of regions, not of countries," Fernandez stressed.

"Latin America and the Caribbean must be united once and for all, because the world has changed geopolitically and no one can be saved alone," he said.
