• The Trump administration is fine with Nvidia selling chips in China.
• Commerce Secretary Howard Lutnick says the best chips will stay within the US.
• Nvidia announced that it has received assurances it can resume selling its H20 chip in China.

The Trump White House says it's content to allow Nvidia to tap into the lucrative Chinese market.

"We don't sell them our best stuff, not our second best stuff, not even our third best," Commerce Secretary Howard Lutnick said on CNBC Tuesday afternoon. "I think fourth best is where we have come out that we're cool."

Nvidia announced on Monday that the Trump administration has signaled it will allow the company to sell its China-specific H20 chip once more. The news sent shares of the world's most valuable company, which eclipsed $4 trillion in market cap last week, even higher.

Nvidia's H20 was designed to be technologically inferior. As Lutnick said, the company also sells three other chips that far surpass the H20's power. Nvidia is already preparing its transition from Blackwell (its most powerful chip) to Blackwell Ultra and has plans for its next superchip, "Vera Rubin."

CEO Jensen Huang has pushed to sell the company's prized chips to China. Before the news, Nvidia said it had lost $8 billion on unshipped orders. The announcement came after Huang met with President Donald Trump at the White House last week.

Lutnick said that the administration shares Huang's view that cutting China off completely from the chips needed to power artificial intelligence advancements won't starve China's AI industry.

"So the idea is the Chinese are more than capable of building their own, right? So you want to keep one step ahead of what they can build so they keep buying our chips, because, remember, developers are the key to technology," Lutnick said.

In the end, Lutnick said, it's better if China becomes reliant on the US for chips.

"So you want to sell the Chinese enough that their developers get addicted to the American technology stack," he said. And that's the thinking. Donald Trump is on it."

• Walmart says tariffs remain "too high," even after recent reductions.
• The company said it would have to raise some prices if import costs didn't come down further.
• It's not yet clear how already-pressured shoppers would respond to price hikes.

President Donald Trump's shifting trade policy is causing headaches for America's largest retailer.

While Walmart CFO John David Rainey welcomed the recent reduction in tariffs, he said the company was not out of the woods yet.

"Let me emphasize, we still think that's too high," he said of the latest rates during Walmart's earnings call on Thursday.

Walmart says it imports about one-third of what it sells in the US from other countries, namely China, Mexico, Canada, Vietnam, and India, and that cargo is flowing.

"There are certain items, certain categories of merchandise, that we're dependent upon to import from other countries, and prices of those things are likely going to go up, and that's not good for consumers," Rainey said.

Rainey added that shoppers were showing signs of being more financially pressured, evidenced by their spending shifting away from general merchandise and more toward food and essentials.

Walmart CEO Doug McMillon added that he didn't think shoppers would tolerate additional price hikes on their grocery bills, which would limit the retailer's ability to shift import costs to other goods in its assortment.

"The first thing that goes through my mind is food inflation," he said. "We've been through a number of years here where prices have gone up on food, and our customers have felt that, and they don't want any more food inflation."

He also said he was hopeful that any long-term policy would address foods that the US doesn't produce in significant amounts, like bananas.

An additional wrinkle for Walmart management is the question of what economists call "price elasticity," or the change in purchasing patterns in response to changes in cost.

American consumers proved resilient during recent years of high inflation and kept on spending even though prices were climbing.

But Rainey said tariffs make it "more challenging to anticipate demand by item," since it's not clear how shoppers would respond to new tariff-related price hikes and retailers are wary of getting stuck holding large amounts of expensive merchandise.

"We'll watch where our price gaps are," McMillon said, "but we'll also watch what customers are telling us and the response that we get from pressure that they're feeling."

While that puzzle is a little more solvable with high-turnover items like food, it's considerably more difficult to predict for seasonal sales events like back-to-school shopping or the holidays — and Walmart has to place those orders now.

And thanks to a quirk of retail accounting, a significant fluctuation in shelf prices could have an outsize impact on the company's financial results in the coming quarters if it has to make large adjustments to its inventory valuation.

"How do you make a quantity call, and what tariff number do you use?" McMillon said.
