Like all other multilateral development banks, the Asian Infrastructure Investment Bank (AIIB), which approved its first loan in November 2016, has adopted Environmental, Social and Governance (ESG) policies. Treating the text as Chinese discourse and using Critical Discourse Analysis as methodological tool, this article unveils socio-political interests beyond its contents and semiotics. We identify areas where the AIIB policies are intertextual with the ones that inspired them, namely those of the World Bank and the regional multilateral development banks, but also important departures from their discursive practice, reflecting the legal culture and strategic interests of AIIB's founders. Both appropriation and colonisation of ‘classical’ ESGs by the AIIB ones lead to reflection on social wrongs associated with development, and suggest solutions for turning development safeguards into meaningful instruments.
