What is your take on US President Donald Trump’s so-called economic D-Day on Iran? Some mainland Chinese and Hong Kong companies are implicated in the new secondary sanctions. Can Trump achieve his goals with these measures or will they backfire? What results will these sanctions bring?

Trump’s D-Day sanctions will either fail to squeeze Tehran very hard and not much happens, or they will be hard-hitting and then the question is whether Iran counter-escalates or surrenders. And the pattern so far is really clear: Iran fears capitulation much more than escalation.

And given that [US Treasury Secretary Scott] Bessent has not listed any clear demands, Tehran will interpret the purpose of D-Day as a measure to force its surrender.

So instead of this leading to an end to the conflict, it will just start another round of the escalatory cycle.
