Thailand's Department of Business Development has referred 36,277 foreign-owned entities holding 305,838 land plots (1.6 million rai) to enforcement agencies for investigation into possible nominee business violations. The probe covers entities with varying foreign ownership stakes; 3,450 entities have 100% foreign ownership, while others operate as joint ventures. Authorities will use the data to verify compliance with investment promotion conditions and identify illegitimate nominee operations, though many holdings may represent legitimate Thai-foreign joint investments.
