Striking farmers block a road near Tandil, Argentina, 17 May 2008

Argentina's four main farm groups have agreed to suspend their strike, which has halted grain exports from a major world supplier.

Representatives of the farmers said Monday the strike will end on Wednesday.

The farm groups said they will allow grain to start moving to market in order to re-establish negotiations with the government on farm policy.

After President Christina Fernandez de Kirchner announced an increase in export taxes in March, the farmers launched a three-week strike. They blocked highways, disrupting agricultural exports and causing food shortages.

They suspended the strike in April to negotiate with the government but announced early this month they would resume their demonstrations.

Ms. Fernandez has said the increased export taxes are aimed at redistributing wealth to poorer parts of society.
