The change comes at a crucial juncture, with Donald Trump about to become US president
Mexico will name a new ambassador to the US, The Hill reports, citing Mexican Foreign Relations Secretariat sources.
The current ambassador Carlos Sada Solana will be replaced by Geronimo Gutierrez, who is currently the managing director of the North American Development Bank. Previously, Gutierrez was the undersecretary for North American affairs at the Foreign Relations Secretariat, The Hill reports.
The announcement is expected to come on Friday, The Hill reports.
The change in appointment comes as relations between the country are strained, as Trump has promised to renegotiate the North American Free Trade Agreement (NAFTA), build a wall along the border that the President-elect says Mexico will fund, deport millions of mexicans and place tariffs on goods manufactured in Mexico.
This post is considered to be Mexico's highest appointment because of the historical closeness between the two countries and because millions of Mexicans currently live in America.
