What led to Adam Castillo’s detention in Myanmar?
The former president of the American Chamber of Commerce in Myanmar, Adam Castillo, was detained upon his return to Yangon on Thursday, according to an associate who spoke on condition of anonymity. Castillo, founder of AGS Myanmar, a security risk management firm, was reportedly investigated for alleged financial misconduct involving former board members. The chamber’s May 29 annual report detailed “suspect transactions” by ex-board representatives, including a $300,000 payment to a Washington-based PR firm in November 2024, which was “collected and disbursed outside AMCHAM Myanmar’s accounts,” according to the document. The report stated the contract was signed by a “former board representative” without board approval, and no funds or services were received by the chamber.
How has the American Chamber of Commerce responded?
The American Chamber of Commerce in Myanmar (AMCHAM) confirmed the investigation but declined to provide further details. Its executive director, Myat Phyu The, stated the organization’s report “covers the issue at hand” and emphasized that “appropriate steps have been taken to safeguard the interests of the organization and its members.” A June 12 statement from AMCHAM reiterated this stance, though it did not specify legal actions against the involved parties. The chamber, which promotes U.S. business interests in Myanmar, has not publicly named the individuals implicated in the case.
What is known about Castillo’s background and activities?
Castillo, a former U.S. Marine officer who served in Afghanistan, founded AGS Myanmar in 2013. The company provides security, commercial cleaning, and pest control services. Castillo also serves as chair of “Republican Overseas Myanmar,” a group established in 2024 to advance “America First policies in Myanmar,” according to his company’s website. Prior to his detention, Castillo attended a business forum in Kuala Lumpur, Malaysia, where he promoted his memoir, *Finding Our Voice*, which chronicles his experiences in Myanmar amid the military’s 2021 coup and subsequent violence. It remains unclear if the book influenced his detention.
How has the U.S. government responded?
The U.S. State Department acknowledged reports of Castillo’s detention but stated it could not comment further “due to privacy considerations.” This aligns with the agency’s usual approach to sensitive cases involving American citizens abroad. Myanmar’s military-backed government has not issued an official statement, as is typical in the country’s ongoing civil conflict. The detention adds to a pattern of increased scrutiny of foreigners in Myanmar, particularly journalists and business figures, since the 2021 coup.
What is the broader context of Myanmar’s political crisis?

Myanmar has been embroiled in a civil war since the military ousted Aung San Suu Kyi in 2021 and violently suppressed pro-democracy protests. The conflict has drawn in ethnic minority militias and pro-democracy guerrillas, creating a volatile environment for foreign nationals. The U.S. and other governments have expressed concern over human rights abuses and the destabilization of the region. Castillo’s case highlights the risks faced by foreign business leaders operating in a country where political tensions and legal transparency remain deeply uncertain.
What happens next in Castillo’s case?
As of now, no formal charges have been announced, and Castillo’s legal team has not publicly addressed the matter. The American Chamber of Commerce’s report suggests the organization is pursuing internal accountability, but the lack of transparency from Myanmar’s authorities leaves many questions unanswered. International observers will likely monitor the case closely, given its implications for U.S.-Myanmar business relations and the broader geopolitical tensions in Southeast Asia.
