I think this whole thing is the New governments half harted effort to show the UN and other institutions that they are willing to go along with their global sustainability development goals. Perhaps to drum up new global investment to Thailand, or to borrow large sums from the IMF or world bank. Whether they follow through on enforcing strict taxation or not is yet to be seen. I suspect by their non reaction that they are not going to be very pro-active on this at first. Might take a few years before they really get moving on this. By then a lot can change.
