China's competition regulators are reportedly slowing down Nvidia acquiring UK chipmaker Arm.

As reported by The Information, Chinese regulators apparently are yet to even begin reviewing the deal which can take as long as six months. The outlet says that given the scope of what this acquisition means, it could well have to go through the review process another one or two times after its initial run.

Meanwhile, Nvidia also reportedly missed the July deadline to submit necessary paperwork with the European Union's own competition regulator, after which the body is on summer holiday until September.

Nvidia revealed in September 2020 that it intended to acquire Arm, though it is facing something of an uphill battle to close the deal. The UK's Department of Digital, Media, Culture and Sport intervened in the acquisition in April citing national security concerns. This followed the country's Competition and Markets Authority (CMA) investigating the deal at the start of 2021. CMA was asked by DCMS to submit a report looking into the merger by the end of July.

Meanwhile, in the US, tech companies including Google, Microsoft and Qualcomm have expressed their concerns about the acquisition to US competition regulators.

Nvidia CEO Jensen Huang has said that he is "very confident" that the deal would close in 2022.
