Not sure, the news said the letter has only been 'leaked' recently (CMIIW)
I can't remember (and too lazy to google it tbh :D) whether we have this kind of news earlier this year or not
As a non-aligned country, we are not that 'special'. Why do you think they block our Su-35 with CAATSA?
US have south Korea, Japan, Australia, etc as a better alternative in the region
Was arms procurement really discussed when President and MoFA met their US counterparts recently?
Even if they did discuss the matter, I don't think meeting automatically means a successful lobby
