There were at least three ink colors manufactured in Thailand—blue, blue-black, and black. I could only get my hands on two of them, and the current analysis is limited to those—blue and black.
The question to answer is obvious—are these Thai inks of the same formulation as those made in Japan?
Smell wise, the Thai inks have a very distinctive phenol odor whereas those made in Japan are almost odor-less. The black ink, though, releases a hint of ammonia.
On paper, both pairs show similar tones. The Thai blue is slightly lighter in color, and the Japanese version occasionally adds some purple sheen. The Thai ink has a higher surface tension.
Re black ink, the Thai one is again slightly lighter and less brilliant than the Japanese ink.
Finally, the chromatography shows that the dye composition is different in both pairs. The differences are bigger in the black inks. But the conclusion is clear—Thai and Japanese inks are different formulations.
Not much can I say about Pilot in Thailand. It started in 1953, and the manufacturing plant was located in Bangkok. The Thai black ink is dated in 2013, and we can assume that the Pilot plant was open until at least that year. As of today, the Pilot Thailand website (http://www.pilotpen.co.th/) is not active, and there is no reference to Thailand in the Pilot Global site.

My thanks to my friend and ink connoisseur Papishdama.
Note (August 2022): It seems that the Thai Pilot was related to the Korean Pilot, a different company than the Japanese one. Korean Pilot is not operating currently.
