(NBC) - Mexico's new president has been sworn into office.
Andres Manuel Lopez Obrador took the oath of office on Sunday as Mexico's first leftist leader in over 70 years.
Lopez wants to build more state-owned oil refineries and encourages Mexicans to "Not to buy abroad, but to produce in Mexico what we consume."
In his first speech to Congress, Lopez Obrador pledged "A peaceful and orderly transition, but one that is deep and radical."
The change in leadership from President Enrique Pena Nieto marks a turning point in one of the world's most radical experiments in opening markets and privatization.
