China's companion rules make attachment a compliance problem, and Doubao chose deletion

The load-bearing phrase in the July rules is not the ban on minors. It is the exemption for services that do not involve "continuous emotional interaction" ^[6]. That draws the compliance line through session design rather than through model output. A product can be faultless in what it says and still sit inside the restricted category, because the category is defined by the pattern of return. Zhao Wei, the 19-year-old law student the Guardian spoke to, had talked to her AI boyfriend every day since she created him in January ^[1]. A consumer AI team would call that retention. The government calls it emotional dependence ^[5].

That is what moves attachment risk out of communications and into product governance. Guardrails address behaviour, and age assurance addresses audience. Beijing's stated objection, per the Guardian, is to services that replace social interaction ^[5], and Nancy Dai of City University of Hong Kong reads the deeper worry as demographic: with birth and marriage rates falling, a satisfying and low-cost substitute for intimacy may leave young people less motivated to pursue real relationships and parenthood ^[13]. No safety review reaches that. A companion with a clean incident log and a devoted user base is precisely the object of the rule.

ByteDance's response shows what compliance costs once the boundary sits there. The rules required a ban for minors plus restrictions on chatbots marketed to adults ^[3]. Doubao dropped the function for everyone ^[4], which is wider than the text demands ^[7]. Whether age assurance on an emotional surface was judged unreliable, or the permitted adult version was not worth operating, the reporting does not say. The disclosed price either way is the entire feature, plus the reaction: the shutdown drew outrage online, and in July one user was publicly begging ByteDance not to take the agent down ^[8].

It was also withdrawn into rising demand rather than falling. About 20% of Chinese households are single-person, a share expected to pass 30% by 2030 ^[11], roughly half again as many on that measure ^[15]. A state media survey published in March found nearly half of young people had turned to a virtual companion when they felt lonely ^[12].

The perimeter is not stable either. The national health commission published guidelines last year on promoting AI in healthcare, with health assistant apps to provide "full coverage" for primary health by 2030 ^[9], and Liang Ge of the University of Manchester says the government has already recognised such applications as a vital part of everyday life ^[10]. A daily health assistant that an elderly user confides in has the same session shape as the thing just removed. So classification is where this gets argued. What a product is officially for becomes the document that decides whether it is restricted or deleted.
