(20)Based on the definition of forced labour specified in ILO Convention No 29 and used in this Regulation, the ILO indicators of forced labour and the ILO guidelines entitled ‘Hard to See, Harder to Count’ set out the most common signs that point to the possible existence of forced labour and should be taken into account when implementing this Regulation. However, those indicators may be insufficient for the identification of forced labour imposed by state authorities, which is based on systemic and global coercive policies that require additional, specifically designed indicators.
