Key US trading partners in Asia have been hit with a fresh wave of uncertainty after America's top court ruled that ⁠many of the tariffs President Donald Trump announced in 2025 are illegal.

After the Supreme Court ruling on Friday, Trump said he would impose new global levies of 15% on goods entering the US.

US customs said on Monday that it would halt the collection of tariffs linked to the signature trade policy that Trump used to launch a ⁠global trade war.

This is a major blow to governments from India to Indonesia, which had spent months negotiating trade deals with Washington. Many had pledged to invest billions of dollars in the US.

While the new tariff rate appeared to be a win for many Asian countries that had originally been hit with higher levies, significant uncertainties remain, analysts have told the BBC.
