President Trump’s dispute with China has landed on the doorstep of Verizon, with Huawei demanding that the American wireless giant pay licensing fees on hundreds of patents, according to two people briefed on the matter.

Huawei, one of China’s largest technology companies and the world’s biggest supplier of networking equipment, accused Verizon in a letter this spring of violating 238 of its patents, the people said. They would speak only on the condition of anonymity because the issue was considered a potential legal dispute.

The letter, earlier reported in The Wall Street Journal, represents a new wrinkle in the tensions between the Trump administration and China.

Mr. Trump has appeared to use Huawei as a bargaining chip in his trade war with China. Last month, he signed an executive order that banned the purchase of equipment from companies posing a national security threat. That includes gear from Huawei, because of its ties to the Chinese government. Huawei officials have denied that it is a security risk and has accused the Trump administration of unfairly targeting the company’s products.
