The Thai foreign minister announced a formal request to join BRICS in June 2024 at a meeting with Russia's Sergei Lavrov.

Will this membership become official in 2024?

The US or allies could put pressure on Thailand not to join what is increasingly seen as a pro-Russian, anti-US group.

The market will resolve YES if Thailand officially joins BRICS, whether or not it is included in the acronym. It will resolve NO otherwise or if this is not confirmed in official media reports before the end of 2024.
