In October 2020, the United States arrested former Mexican Defense Secretary General Salvador Cienfuegos Zepeda on drug conspiracy charges, accusing him of accepting bribes to aid a Mexican cartel in evading law enforcement and transporting drugs into the United States. Cienfuegos's arrest sparked diplomatic protests from Mexico, which negotiated to gain Cienfuegos's release before exonerating him and publicizing the U.S. investigation file in what the United States called a breach of the countries’ mutual legal assistance treaty. The incident also prompted Mexico to pass a new law curtailing cooperation with foreign agents and potentially imperiling the long-standing U.S.-Mexico alliance in the fight against cross-border drug trafficking.

美国以毒品罪名逮捕墨西哥前国防部长对未来的禁毒合作构成挑战

2020 年 10 月，美国以贩毒罪名逮捕了墨西哥前国防部长萨尔瓦多·西恩富戈斯·泽佩达，指控他收受贿赂以帮助墨西哥卡特尔逃避执法并将毒品运往美国。西恩富戈斯的被捕引发了墨西哥的外交抗议，墨西哥通过谈判让西恩富戈斯获释，然后才免除他的罪名并公布美国的调查档案，美国称其违反了两国的司法互助条约。该事件还促使墨西哥通过了一项新法律，限制与外国代理人的合作，并可能危及长期以来在打击跨境贩毒方面的美墨联盟。
