PowerChina and China State Construction Engineering (CSEC) were accused of participating in infrastructure projects that raised serious transparency concerns. PowerChina, the main contractor for the €94.1 million Sava Bridge project and responsible for demolishing the old bridge, and CSEC, which is involved in constructing the new bridge’s steel structures, were linked to a contracting process that bypassed Serbia’s public procurement law. The companies were also associated with a lack of transparency, as full contract documentation for the Sava Bridge has not been disclosed to the public, with authorities invoking “business secrecy,” limiting access to information and public scrutiny. PowerChina’s involvement in additional large-scale projects, including infrastructure tied to the 2027 World Expo, further reinforced concerns highlighted by civil society groups and the European Commission that repeated reliance on such agreements erodes institutional checks and increases corruption risks.
