In December,a California Importer Contracted with a Guatemala Exporter for a Plane

In December,a California importer contracted with a Guatemala exporter for a plane load of roses to be shipped to Los Angles from Guatemala City the first week in February.Because of a regional hail storm in January,the exporter's usual sources of supply dried up to the extent that he could not obtain sufficient quantities of quality roses in Guatemala,so arranged for a shipment from the Cameron Highlands in Malaysia.When the shipment arrived in Los Angles,the importer refused it-based on the fact the roses didn't come from Guatemala.Give the legal arguments of each party.
