In April, Washington restricted the sale of Nvidia's China-specific "H20" chips, which led to a drop in demand.Nvidia said it had incurred a $4.5bn charge as a result - but its initial forecast for the impact on business was significantly higher at $5.5bn.

Mr Huang said on Wednesday he expected demand for AI computing to "accelerate".Analyst Dan Ives said the company's earnings and guidance were "a very positive result for Nvidia and the tech world after a Twilight Zone tariff battle".Nvidia was the last major tech firm to report during a strong earnings season for tech companies whose shares have surged in recent weeks.

Changes in global trade policies also loomed large in the company's forecast.New export controls and tariffs have increased the complexity and cost of its supply chain, and may continue to do so, the company said.

Nvidia said it planned to increase manufacturing in the United States to help tackle the issue.

Last week, Mr Huang criticised the US rules blocking exports of advanced computing chips to China.More surprising, perhaps, is the opinion of his American competitors in California and Oregon who, you might think, would be cracking open something a bit special to celebrate.

"This looks horrible from our perspective. We don't like it one bit," says Rex Stults, vice-president of industry relations at Napa Valley Vintners, which represents 540 wineries in the sunny slopes of California's most famous wine region."Wine is an international product. Even here in the Napa Valley, our wineries primarily get their corks from Portugal, and their oak barrels, a key component in winemaking, from France.

Mr Stults adds: "They're already expensive and the potential is that they will get more expensive."Also, trade wars cut both ways. He says the tariffs announced against Canada are having a devastating impact on US wine exports.
