Maybe it had something to do with Thailand in the thick of re-directing goods made in China being re-labelled made in Thailand.
Also the projected tariff charge put on Chinese solar panels is making Thailand nervous....
Thailand is caught between a USA mandate that they have to agree to, before any trade talks can take place. Thailands love affair with aiding and abbeting Chinese tariff dodging games by using Thailand as a transiting hub must come to an end.
Thailand can no longer sit on the fence and play dumb.
