Well, Thailand is after tourists because they mean income. If you think of some locations (Pattaya, Patong, Hua Hin, Chiang Mai, etc.), why would they not care/write about returning expats, esp. as a good number left during the pandemic. And expats, obviously, stay longer than tourists, and can be of importance for local economies (e.g. Pattaya, Phuket). But, using your argument, why write about tourist arrivals at all?
