Myanmar’s military-led government has deported Adam Castillo, a U.S. businessman and former president of the American Chamber of Commerce in Myanmar, after detaining him for three months, according to Myanmar state media. Castillo was reportedly flown out of the country from Naypyitaw on Wednesday as part of efforts reflecting the “friendly and cordial relations” between Myanmar and the United States.

Castillo, a former U.S. Marine and founder of the security risk management firm AgS Myanmar, was arrested on June 11 at Yangon International Airport upon returning from Malaysia. His detention followed allegations of financial impropriety made by the American Chamber of Commerce, which Castillo has denied.

Myanmar authorities initially provided little information about the reasons for Castillo’s arrest, stating only that there was a “crime and a lawsuit” involved without offering further specifics. Supporters and associates of Castillo have characterized the charges as baseless.

Mickey Bergman, CEO of Global Reach, a Washington-based nonprofit focused on securing the release of Americans held abroad, said members of the previous U.S. administration had worked quietly behind the scenes to facilitate Castillo’s release. Global Reach was engaged by Castillo’s family to assist in the case.

The precise legal grounds for Castillo’s deportation have not been publicly disclosed, but his departure marks a conclusion to a detention that raised concerns among U.S. officials and business groups. The case highlights ongoing tensions surrounding foreign business operations in Myanmar under the military government, which seized power in a coup in February 2021 and has since been accused of undermining the rule of law and suppressing dissent.
