I haven't traveled outside the US very much but when I was in China, I took a 2 hour domestic flight on Shenzhen Airlines and they served hot meals both ways for free with 2 or 3 choices of meal. I was impressed, I've never received that kind of service except on long international flights.
This was the hot teriyaki chicken, rice, and vegetables with a box containing a roll, banana, pickled vegetables, and candy.
The Chinese equivalent of "how are you" is "have you eaten yet?" I think there's a lot more emphasis on having a proper hot meal than in many other places.
You can even see that attitude reflected in government COVID supplies. In Japan the delivered supplies for people in quarantine were almost all instant processed foods. In China, lockdown supplies had tons of fresh vegetables and meats. Ironically, that made food deliveries more expensive and difficult but there was never any talk of replacing fresh food with processed food.
