I think there are. One should explore the exact rules and practices regarding "gifts". And I draw your attention to the fact that our billionaire PM has received one of those "gifts" THB 20M I think, from his children. This was published here recently.
This also leads me to think that moving to tax overseas income and not ruling against these "gifts" was indeed directed against foreigners, as we are much less likely to benefit from such donations. It could have been intentional, or not, I don't want to overestimate them.
