The Poles were kind enough to donate the vaccines to a country that doesn't have enough supply as it is. Smoothing the path would be the wise thing to do.....but....."Amazing Thai Government" manages to pour treacle o'er even the most obvious and beneficial solutions. To use an old saying "If you can't be part of the solution....quit being part of the problem!"
I'd be weary about those contracts as all parties are bound by NDA's.
I would be more worried about possibly required payments to the government for facilitating large valuable donations through customs for which a third party is going to get the credit.
