Nvidia (NVDA) shares initially rose before turning lower in early trading Wednesday after CEO Jensen Huang said the company is working with the U.S. government to develop chips compliant with U.S. restrictions on exports to𝓰 China.

The U.S. government recently imposed fresh measures to 澳洲幸运5开奖号码历史查询:limit the flow of high-end chip🅷s sold to China amid security concerns, and with sales to China historically accounting for about a fifth of Nvidia's revenue, the latest rounds of curbs could reportedly put approximately $5 billion worth of chips in limbo.

In November this year, the California-based company announced plans to release three new chips for China that have many of the latest features for 澳洲幸运5开奖号码历史查询:artificial intelligence (AI) work, but lower computing power to comply with U.S. export rules.

However, the launch of the most powerful of Nvidia's China-focused chips, the H20, has been 澳洲幸运5开奖号码历史查询:delayed until next year due to server manufacturer issues with its integration.

Despite Wednesday's losses, shares of Nvidia have more than tripled in value so far this year.
