Amid trade war ambiguity, Trump signals he will place further tariffs on Chinese tech

U.S. President Donald Trump on Sunday bore down on his administration's latest message that the exclusion of smartphones and computers from his "reciprocal" tariffs on China will be short-lived, pledging a national security trade investigation into the semiconductor sector.

Those electronics "are just moving to a different Tariff 'bucket,'" Trump said in a social media post. "We are taking a look at Semiconductors and the WHOLE ELECTRONICS SUPPLY CHAIN in the upcoming National Security Tariff Investigations."

The White House had announced the exclusions from steep reciprocal tariffs on Friday.

U.S. Commerce Secretary Howard Lutnick earlier Sunday said that critical technology products from China would face separate new duties, along with semiconductors, within the next two months.

The exclusions announced on Friday were seen as a big break for technology companies such as Apple and Dell Technologies that rely on imports from China.

Trump's back-and-forth moves on tariffs have kicked off a trade war with China and prompted the wildest swings on Wall Street since the COVID-19 pandemic, which began in early 2020. The benchmark S&P 500 index is down more than 10 per cent since Trump took office on Jan. 20.

Lutnick said Trump would enact "a special focus-type of tariff" on smartphones, computers and other electronics products in a month or two, alongside sectoral tariffs targeting semiconductors and pharmaceuticals. He said those new levies would fall outside Trump's so-called reciprocal tariffs, under which total levies on Chinese imports climbed to 145 per cent this week.

"He's saying they're exempt from the reciprocal tariffs, but they're included in the semiconductor tariffs, which are coming in probably a month or two," Lutnick said in an interview on ABC's This Week, predicting that the levies would bring production of those products to the United States.

"These are things that are national security, that we need to be made in America," he said.

Beijing increased its own tariffs on U.S. imports to 125 per cent on Friday, striking against Trump's levies. China said on Sunday that it was evaluating the impact of the exclusions for the technology products implemented late on Friday.

"The bell on a tiger's neck can only be untied by the person who tied it," China's Ministry of Commerce said.

Billionaire investor Bill Ackman, who endorsed Trump's run for president but has criticized the tariffs, on Sunday called on him to pause the broad and steep tariffs on China for three months, as he did for most countries last week.

"If President Trump were to pause the China tariffs for 90 days and reduce them temporarily to 10 per cent, he would achieve the same objective in causing U.S. businesses to relocate their supply chains from China without the disruption and risk to these businesses in the short term, and he would have time to negotiate a deal with China," Ackman wrote on X, formerly Twitter.

Sven Henrich, founder and lead market strategist for NorthmanTrader, was harshly critical of how the tariff issue was being handled on Sunday.
