The company’s decision to halt work with Huawei was earlier reported by Reuters. Intel declined to comment, and Qualcomm did not respond to requests for comment.

Major American wireless companies have effectively been blocked from buying Huawei’s telecommunications equipment for years, but the company’s business has grown rapidly in Africa, Asia and Europe, where its affordable prices have been embraced by consumers and by phone companies that use its antennas, base stations and other hardware to make wireless networks.

In recent months, the United States has stepped up its campaign against Huawei, which it has said poses a national security risk. American authorities have worked to persuade allies like Britain and Germany to block the use of Huawei telecommunications equipment. But the efforts have had limited success, as many countries rely on Huawei gear in the race to build up fifth generation, or 5G, wireless communication networks.

Last week, President Trump issued a ban prohibiting American telecommunications firms from installing foreign-made equipment that could threaten national security. The order instructed the commerce secretary, Wilbur Ross, to stop transactions “posing an unacceptable risk.” Although the order did not single out specific companies, it was widely believed to be directed at Huawei and others in China’s tech sector.

The actions put pressure on American allies that have so far resisted urging from the Trump administration to issue complete bans against Huawei. James Lewis, a senior vice president and the director of the technology policy program at the Center for Strategic and International Studies, said that most European countries would prefer a softer approach.

“I don’t think Europeans realize the extent of the strength of feelings in the U.S. that we need to block Huawei,” Mr. Lewis, a former official at the State and Commerce Departments, said.

China has not said whether it plans to retaliate against the United States in response to Mr. Trump’s move. On Monday, shares in Qualcomm, Infineon, Intel and Alphabet, Google’s parent, all fell. Apple, which depends on the Chinese market for a large portion of its revenue, also dropped amid concerns that the tech battle between the two powers made it a potential target.
