Commerce Ministry and Interior Ministry teams raided Koh Phangan, checking resorts, rental villas, a cannabis shop chain and a luxury villa for nominee arrangements. Thai directors and shareholders in several companies were questioned on how their investments were funded. Authorities say 104 companies holding 124 land plots in Surat Thani are being reviewed for land ownership. Nominees face up to 3 years' jail or a fine of 100,000-1,000,000 baht. Foreign-linked businesses should check that their Thai directors and shareholders can document the source of their investment and their real role in the company. Rental villas paid online from abroad were also flagged as possible tax avoidance.
