Thailand's Commerce Ministry is tightening company registration rules with stricter checks on shareholders and investment fund sources. The enhanced framework expands inspections beyond initial registration to monitor subsequent changes in ownership structures, director appointments, and authorized signatory designations. Foreign investors and nominee arrangements will face increased scrutiny, though the government emphasizes the goal is preventing illegal structures (not discouraging legitimate investment) by enabling better inter-agency coordination and risk-based screening to catch potential breaches while maintaining transparency.
