China's top market watchdog announced on September 15 a decision to launch further probe into Nvidia for anti-trust violations after a preliminary investigation.

The State Administration for Market Regulation (SAMR) said in an online statement that Nvidia had violated China's anti-monopoly law and a 2020 decision by the market regulator on Nvidia's acquisition of Mellanox Technologies.

In 2020, the SAMR conditionally approved the acquisition after an antitrust review that began in 2019. The deal was subject to multiple restrictive conditions due to concerns that the merger could exclude or restrict competition in global and Chinese markets for GPU accelerators, dedicated network interconnect equipment, and high-speed Ethernet adapters.
