China’s Belt and Road Initiative has expanded Chinese technology across the Western Balkans, particularly in telecommunications and surveillance infrastructure, prompting national security and privacy concerns as governments and operators reassess supplier risk. In Serbia, Telekom Srbija Group has moved away from Huawei and toward Ericsson and Nokia for 5G deployment under pressure tied to Western financing and broader integration goals, reflecting a wider push to reduce reliance on Chinese vendors in critical networks.
The shift aligns with U.S.-backed efforts such as the Clean Network initiative, which sought to exclude what Washington described as untrusted Chinese technology from sensitive digital infrastructure. At the same time, the regional contest over telecom infrastructure has been compounded by cyber threats: Telekom Srbija Group was reportedly hit by a cyberattack earlier in the year that the company attributed to Russian hackers, underscoring how Chinese investment, Russian cyber activity, and Western security policy are converging in the Balkans’ communications sector.
