Africa is adjusting to the new reality of US President Donald Trump’s tariffs, with countries on the continent facing some of the highest export charges.

President Trump’s executive order carved out a special tariff on goods shipped indirectly to the United States by way of other countries.

In the wake of US President Donald Trump's latest tariff blitz on dozens of economies, China has reiterated a stern warning against protectionism amid growing concern that it will "harm the interests of all parties".

China’s cyber regulator on Thursday said it had held a meeting with Nvidia over what it called “serious security issues” with the company’s artificial intelligence chips. It said US AI experts had “revealed that Nvidia’s computing chips have location tracking and can remotely shut down the technology”.

China's cyberspace regulators have summoned Nvidia over security concerns about its H20 chips. They claim the chips can be tracked and turned off remotely.

China state media is calling for Nvidia Corp. to prove that its H20 chip is secure, saying it can’t allow flawed chips into the country.
