Points out the uneven ("completely unfair!" as Trump would say) relationship between US and China on trade. China bans American companies for free speech, and monitors the statements of all their employees. Meanwhile, US does not retaliate or enforce similar standards for China, and Chinese startups are allowed full access to US market.
Before, Chinese companies weren't able to penetrate US market, but TikTok is the first example of one that can. While Twitter/FB are banned in China, TikTok is allowed full access to US market.
