Mexican President Enrique Pena Nieto is visiting California at the invitation of Gov. Jerry Brown.
The two-day tour starts in Los Angeles on Monday and comes less than a month after Brown visited Mexico.
The two are expected to address hundreds of Mexican and Mexican-American leaders at the Millennium Biltmore Hotel in Los Angeles.
It's not known what Pena Nieto plans to say, but Mexico and the U.S. share concerns about a host of issues, including immigration and pollution. Mexico also is California's largest export market.
During the governor's trip to Mexico last month, he signed nonbinding agreements on trade, education and environmental cooperation.
