The Anti-Slavery and human trafficking statement says:

n 2016, we introduced self-assessment monitoring to our Supplier Code for prioritised suppliers. Suppliers were selected for assessment based on three factors; their strategic significance to Rolls-Royce; the nature of the services they are contracted to provide (i.e. international logistics providers); and/ or, their geographical location. Countries have been identified as potentially higher risk using externally published sources, including:

Corruption Perceptions Index, Transparency International

Global Competitiveness Index, World Economic Forum

Global Slavery Index, Hope for Children Organisation"

However it does not say specific places.

Whilst the statement does not give a clear overview on which countries and which facilities/suppliers they consider "high risk" they do mention the following:
