Commentary Ch. II Paragraph 23

Enterprises may also engage with suppliers and other entities in the supply chain to improve their performance, in co-operation with other stakeholders, including through personnel training and other forms of capacity building, and to support the integration of principles of responsible business conduct compatible with the Guidelines into their business practices. Where suppliers have multiple customers and are potentially exposed to conflicting requirements imposed by different buyers, enterprises are encouraged, with due regard to anti-competitive concerns, to participate in industry-wide collaborative efforts with other enterprises with which they share common suppliers to coordinate supply chain policies and risk management strategies, including through information-sharing.
