After Brazilian President Dilma Rousseff demanded an emergency meeting with her minister of justice over the leaked NSA documents that revealed the U.S. spied on Brazil's president and Mexico's presidential candidate Enrique Peña Nieto, the Mexican government has requested an explanation from the U.S.  

According to CNN, Mexico's Secretariat of Foreign Relations (SRE) summoned the U.S. Ambassador to Mexico Anthony Wayne on Monday, September 2. Likewise, they requested that President Obama's government undertake "a thorough investigation" on the alleged spying against Mexican President Enrique Peña Nieto.

In a statement, the SRE said, "the Chancellery has made a note of the various versions the media has published regarding the alleged espionage against Mexican citizens within the American National Security Agency," Sin Embargo reported.

"Without prejudging the accuracy of the information contained in the reports, the Mexican Government categorically rejects and condemns any efforts to spy on Mexican citizens in violation of international law. This type of practice is contrary to the United Nations Charter and to the jurisprudence of the International Court of Justice," the statement continues.

"Given the above, the Government of Mexico has asked the U.S. government, by diplomatic note, for a thorough investigation and, as applicable, to determine the corresponding responsibilities," the statement concludes. 

Mexico's request comes after American journalist Glenn Greenwald revealed on a Brazilian television channel a series of documents on the alleged espionage actions committed by the American government against the President of Brazil and then-presidential candidate, Enrique Peña Nieto.
