Huawei är helt klart dugliga till att göra mycket av sin egen teknik själva, men även deras egna systemchip bygger på ARM-arkitekturen. Nu berättar BBC att företaget har fått order om att sluta arbeta med Huaweis dotterbolag HiSilicon.

Både ARM och Huawei har uttalat sig i frågan.

"ARM is complying with the latest restrictions set forth by the US government and is having ongoing conversations with the appropriate US government agencies to ensure we remain compliant. ARM values its relationship with our long-time partner HiSilicon and we are hopeful for a swift resolution on this matter."

"We value our close relationships with our partners, but recognise the pressure some of them are under, as a result of politically motivated decisions. We are confident this regrettable situation can be resolved and our priority remains to continue to deliver world-class technology and products to our customers around the world."

Exakt vad detta betyder är ännu inte helt klart, men det gjorde inte Huaweis situation enklare i alla fall.
