Thailand has a way of pulling numbers from anywhere and lobbing them out to prove their "specialness."
For the Thais who depend on tourism for their income, I am happy to see an upswing, though I have serious doubts that all of those arrivals were actually tourists.
It is improving. You can only hope the early arrivals don't get fleeced rotten, as was common behaviour before, so the trend can continue in a positive manner.
