It's not impossible, but you'd think they come up with a better front company than bytedance, of all companies. It's like China accusing that McDonalds is a spy front.
Perhaps, but China really doesn't have a lot of companies with offices in the West. When China tries to buy Western countries they are often blocked for the same national security reasons, as has happened several times in Canada.
A nondescript consumer appliance or clothing "sales office" is infinitely better than bytedance, a company that has received significant flak in the media. The Biden administration's policy of "small yard, high fence" means that unless you're trying to import chips, AI tech, drones, or battery tech, you're probably fine. Nobody is going to blink an eye at some Chinese company trying to sell rice cookers.
