Beijing has urged local companies to avoid using Nvidia Corp.’s H20 processors, particularly for government-related purposes, complicating the chipmaker’s attempts to recoup billions in lost China revenue after the Trump administration reversed an effective US ban on such sales.

Chinese authorities have urged local companies to avoid using Nvidia's H20 processors, particularly for government-related purposes, Bloomberg News reported on Tuesday, citing people familiar with the matter.

The manager said that for chips like the H20, demand depends heavily on large corporations, which are reluctant to buy the products of Nvidia, a United States-based semiconductor company, after the Cyberspace Administration of China summoned the US company for alleged cybersecurity threats in late July.
