Hi Joshua,
I assume the bombing activity is over for this round.
Direct and Indirect damage has been achieved.
It has been reported that a number overseas tourists (e.g. Hong Kong) have decided to postpone their trips to Thailand.
Obviously the relevant government agencies have beefed up their security surveillance.
The perpetrators are on the run.
A number of governments have announced travel advisory, which they “must do”, as if they do not do, and some of their citizens are injured in incidents there is a huge political / financial liability.
It seems that this time the Chinese tourist (however not low-cost Chinese) has been the key target from both bombing locations.
Ploenchit / Nana / Sukhumwit are not known to be Chinese tourist area. There are no attractions in this area, except for Emporium (Sukhumwit Soi 24).
These are my inputs.
Your brother,
Kari
