Why? If what you assert is true, who but the EU has authority to seize Russian planes? Thailand sure doesn't and, as it is a substantial trading partner of Russia, would never do so (even if it could).
So what? Thailand is not subject to US sanctions' restrictions on other countries. Thailand does a lot of business with Russia and it has buggger-all to do with the sodding US or its sanctions.
Why? Thailand has pretty good air safety record compared to many western countries and it's likely that they use the same (Boeing) parts when necessary.
One who has no reason whatsoever to make up a story that she was extorted by Thai place of 27,000 baht ????.....

"Would you trust your life or heath to Thais? Fake vaccine? Expired vaccine? Wrongly stored vaccine? How about complications after vaccine? What are the Thai documents worth, if get, to prove vaccination?"
Unmitigated garbage.

Really? Where exactly was he reported as saying that?
The OP did not reference it, neither did The Nation, nor the report on the same subject in the Bangkok Post.
