Nvidia boss Jensen Huang has blasted US rules that blocked exports of advanced computing chips to China, arguing that they were backfiring against American companies.
At a press conference at the annual Computex conference in Taipei, Taiwan, he called the policies a "failure".
His comments come just days after the Trump administration said it was dropping rules blocking exports to China entirely and restricted sales to dozens of other countries.
The measures, announced in the final days of Joe Biden's presidency drew fierce pushback from tech companies, including Nvidia.
The US started imposing controls on exports related to semiconductors during Trump's first term, citing concerns about letting technology with potential military use fall into the hands of companies connected to the Chinese government.
The Biden administration tightened the restrictions significantly.
During Biden's four-year tenure, Nvidia's share of the Chinese market dropped from 95% to 50%, Mr Huang said on Tuesday.
He argued that the restrictions had pushed Chinese companies toward home-grown alternatives, spurring Chinese investment in the industry.
"The fundamental assumptions that led to the AI diffusion rule in the beginning, in the first place, have been proven to be fundamentally flawed," he told reporters.
