By Karen Freifeld July 10 (Reuters) - The U.S. loosened export controls on the United Arab Emirates on Friday, making it easier to export Nvidia AI chips, military equipment, commercial satellites and spacecraft in a boost to relations between the two allies. The announcement underscores strengthening U.S.-UAE relations, with the Gulf ally playing an increasingly important role in Washington's strategy toward Iran, while creating revenue opportunities for U.S. companies, particularly tech firms.
