US Removes Myanmar Tycoon's Daughter From Sanctions List
The United States removed Theint Win Htet from its Burma sanctions list on Friday, Oct. 9. Al Jazeera reported the delisting on Oct. 10.
She is the daughter of Myanmar businessman Thein Win Zaw, founder of the Shwe Byain Phyu Group of Companies. In January 2024, the Treasury Department under the Biden administration designated the group and members of Thein Win Zaw's family. A designation freezes any U.S. assets and prohibits Americans from dealing with the person. Treasury said the group supplied fuel to Myanmar's military and owned at least 20 firms with close ties to military leadership.
She challenged the designation in U.S. federal court. Her first lawsuit against the Biden administration was dismissed last year. She filed a second complaint in July, arguing she has no role in her father's business. After the delisting, her lawyer, Washington, DC-based sanctions lawyer Erich Ferrari, filed a notice with the federal court in Washington on Friday to voluntarily dismiss the lawsuit.
Court papers described concrete effects on her daily life. Her U.S. credit cards were blocked, her foreign bank accounts were restricted, and she abandoned her master's degree at Columbia University in New York. She now lives in Thailand with her mother, who was removed from the U.S. sanctions list last year.
Treasury's sanctions administrator confirmed the action in its own records. The OFAC Recent Actions page lists a Burma-related Designation Removal dated October 09, 2026 as a Sanctions List Update, as shown in OFAC's listing.
Other recent steps in U.S.-Myanmar relations include three reported developments. In a July 25, 2025 report, Reuters stated the United States had lifted sanctions designations on several allies of Myanmar's ruling generals that had been imposed under former President Biden. On Sept. 16, 2026, Reuters reported that Myanmar's military-backed government freed U.S. citizen Adam Castillo, who had been detained since June. On Oct. 8, 2026, Reuters reported that the United States had opened direct talks with Myanmar's generals.
The broader context here is the use of family-member designations as both enforcement and diplomacy. For sanctions practitioners, the case illustrates how Treasury has applied pressure beyond principal commercial actors to immediate relatives, and how those relatives can contest the factual basis through litigation. The delisting followed a second complaint focused narrowly on lack of operational role.
Looking at what this means for U.S. policy, each step is discrete in legal terms. Sanctions decisions, a detainee release, and direct engagement are moving in parallel. Whether that channel widens will depend on what Washington and Myanmar's generals put on the table next, and whether Treasury treats other petitions on similar factual grounds in the same way.
