I was tweeting with @MarkChiangMai at All Points East and found out the the FCO (Foreign and Commenwealth Office ) for the UK still has a number of Isaan provinces under advisory.
He has to reroute at least 1 tour group and I asked why. Here is the answer
"We advise against all but essential travel to 25 provinces in
Thailand (including Bangkok), which are affected by flooding, as
identified by the Thai authorities. The affected provinces are: North;
(Phichit, Nakhon Sawan and Uthai Thani) Central; (Chai Nat, Sing Buri,
Ang Thong, Phra Nakhon Si Ayutthaya, Lopburi, Saraburi, Suphan Buri,
Nakhon Pathom, Pathumthani, Nonthaburi, Samutsakhon and Bangkok)
Northeast; (Ubon Ratchathani, Khon Kaen, Srisaket, Roi-et, Surin,
Mahasarakham and Kalasin) Eastern; (Chacheongsao, Nakhon Nayok and
FCO Thailand website.
This as you can read are identified by Thai authorities. This is another case of the inept Thai Government. They would be complaining loud and often if another country presented a wide ranging announcement like this. I have seen them go apeshit before when another government made this type of general statement. Screaming for clarification.
I do not have knowledge of all the provinces in the warning, but travel from Khon Kaen to Mukdahan enroute to Lao PDR is certainly clear as well as many other routes.
I would ask whose side they were on, but we know already
