A tyre factory in Zrenjanin that received 96 hectares of land from the state free of charge, plus €83.5 million in state aid. Around 500 Vietnamese workers on its construction site lived in barracks, with their passports taken from them; Linglong says they were hired by a contractor. In 2025 US Customs banned imports of its tyres, citing evidence of nine indicators of forced labour, which Linglong calls completely incomprehensible. Prosecutors in Zrenjanin are examining a criminal complaint alleging human trafficking.
