LAS VEGAS - The CES 2019 gadget show, which kicks off Sunday, will showcase the expanding influence and sway of China's rapidly growing technology sector. But some of its firms are stepping back from the spotlight amid rising U.S. national-security concerns over Chinese tech and a trans-Pacific trade war launched by President Donald Trump. Last year, a top executive of the Chinese telecom firm Huawei delivered a CES keynote address critical of AT&T's abrupt cancellation of plans to sell a Huawei phone following espionage concerns raised by the U.S. government. This year, Huawei's chief financial officer was arrested in Canada at the behest of the U.S.; Meng Wanzhou, daughter of Huawei's founder, now awaits U.S. extradition. No Chinese technology executives will deliver CES keynotes in Las Vegas this week.

President Donald Trump is poised to hike the prices of Chinese-made technology products that might include flat-screen TVs and ultrasound machines for American buyers. They could be among tech imports worth up to $50 billion on which Trump is preparing to slap 25 percent tariffs in response to complaints Beijing steals or pressures foreign companies to hand over technology. The White House has yet to release a final list of products. A tentative version in April ran the technology gamut from TVs and telecoms equipment to medications and industrial chemicals. It would be the first direct impact on American consumers of the dispute over a state-led technology development strategy the White House says violates Beijing's free-trade commitments and hurts foreign competitors.

According to the official, May would tell the summit that "it is worth stepping back to recall that the West, led by the U.S., devised the global rules-based system to enable our citizens to benefit from globalization while providing reassurance that we would all play by a common set of rules."
