China has pretty propaganda-heavy testing infrastructure - they do heavily publicised one-off mass testing of entire cities which the state media points to as proof of their superiority over other countries which aren't doing that, but outside of that testing appears to be extremely questionable. They've had pretty astounding incidents like not testing people hospitalized with Covid symptoms in the one province which had known, uncontrolled community spread at the time at a point when Western countries (or at least the UK) were systematically testing anyone who went near a hospital.
