MEXICO CITY, Jumada II 28, 1437, April 06, 2016, SPA -- Mexico's government on Tuesday unexpectedly changed two of its top officials responsible for U.S. relations, citing concerns about an increasingly anti-Mexican climate across the border, according to Reuters. Carlos Sada, previously the consul in Los Angeles, was named ambassador to the United States while Paulo Carreno, one of President Enrique Pena Nieto's communications chiefs, was appointed the deputy foreign minister for North America. The new ambassador must still be approved by the Senate. "We have been warning that our citizens have begun to feel a more hostile climate," Foreign Minister Claudia Ruiz Massieu told local radio after the announcement. "This (anti-Mexican) rhetoric has made it clear that we have to act in a different way so that this tendency being generated doesn't damage the bilateral relationship," she added. --SPA 02:12 LOCAL TIME 23:12 GMT www.spa.gov.sa/w
