MEXICO CITY, April 30 (Xinhua) -- Mexican President Claudia Sheinbaum on Thursday rejected foreign interference in the country's internal affairs after the United States requested the extradition of a state governor and nine other officials it accuses of arms and drug trafficking.

Given the absence of reasonable proof of wrongdoing, the accusations could be politically driven, Sheinbaum said during her daily press conference.

"Defending sovereignty, as we have done so far, and the rule of law must be based on evidence," she said, stressing that "We will not allow any foreign government to come and decide the future of the Mexican people."

This marks the first time in the history of Mexico-U.S. bilateral ties that Washington has accused a high-ranking official still in office from Mexico, namely Sinaloa Governor Ruben Rocha, of criminal activity, Sheinbaum said.

Mexico's Attorney General's Office has opened a "parallel" investigation into the allegations, she said. "My position on these events is truth, justice, and the defense of sovereignty ... If there is no clear evidence, it is evident that the objective of these charges by the (U.S.) Department of Justice is political."

Evidence presented so far by U.S. authorities consists of a notebook with handwritten notes identifying individuals by nicknames alongside amounts allegedly paid them by drug traffickers.

Bilateral ties have been strained by a recent discovery that the Central Intelligence Agency agents have been taking part in anti-narcotics operations on Mexican soil without the consent of the Mexican federal government.

All this comes amid preliminary talks ahead of the scheduled review of the United States-Mexico-Canada Agreement for free trade.
