WASHINGTON/BEIJING--A U.S. bid to block China's Huawei Technologies from buying vital American technology threw into question prospects for sales at some of the largest tech companies and drew a sharp rebuke from Beijing, further ratcheting up tensions over trade.
Shares of Huawei's U.S. suppliers fell on fears the Chinese firm would be forced to stop buying American chips, software and other components after the Trump administration banned it from buying U.S. technology without special approval.
Huawei, the world's biggest telecoms equipment maker, said that losing access to U.S. suppliers "will do significant economic harm to the American companies" and affect "tens of thousands of American jobs."
"Huawei will seek remedies immediately and find a resolution to this matter," the company said in a statement.
The U.S. crackdown, announced on Wednesday, was the latest shot fired in a U.S.-China trade war that is rattling financial markets and threatening to derail a slowing global economy. Trade talks had looked close to collapsing in the past week after a dispute over Chinese changes to a draft text prompted the United States to hike tariffs on Chinese goods and Beijing to retaliate with higher duties on U.S. products.
Chinese Commerce Ministry spokesman Gao Feng said the United States should avoid further damaging relations between the world's two largest economies, and accused Washington of trade protectionism. "China will take all the necessary measures to resolutely safeguard the legitimate rights of Chinese firms," Gao told reporters.
The Foreign Ministry also announced the formal arrest of two Canadian citizens who were detained shortly after Canada arrested Huawei Chief Financial Officer Meng Wanzhou in December. Meng faces extradition to the United States on charges that she conspired to defraud global banks about Huawei's relationship with a company operating in Iran. She and the company deny the charges.
While China has made no specific link between the detentions of the two men and Meng's arrest, experts and former diplomats say they have no doubt it is using their cases to pressure Canada.
The U.S. Commerce Department said on Wednesday it was adding Huawei and 70 affiliates to its "Entity List," which bars them from buying components and technology from U.S. firms without government approval. It later revised the number of affiliates down to 68.
