Mexico's top diplomat will make a two-day visit to immigrant-friendly California amid strained relations between his country and the US over President Donald Trump's border wall and immigration and trade proposals. <br/><br/>Mexico's Foreign Relations Secretary Luis Videgaray is expected to meet today with Governor Jerry Brown and state legislative leaders in California's capital. He will later head to Los Angeles to announce support for young immigrants whose protection from deportation is being terminated by Trump and meet with business and community leaders. Officials at the Los Angeles consulate said he also plans a trip to Washington later in the week.<br/>'<br/>The trip comes at a critical time in relations between the two countries. In the last few weeks, Trump has stepped up efforts to build a wall on the US-Mexico border and moved to end the program that let roughly 800,000 immigrants –three-quarters of them Mexican — allow to work in the country even though they lack immigration status.
