The report by China Labor Watch highlights the precarious conditions faced by foreign workers in Serbia, specifically at two Chinese-owned companies, the Zijin Copper Mine and Linglong Tire Factory. Through interviews conducted between July and October 2024, workers from China, India, Nepal, Zambia, and Indonesia reported experiences that align with the International Labor Organization's (ILO) indicators of forced labour. Key issues identified include excessive working hours without overtime pay, retention of identity documents, restricted freedom of movement, high agency fees leading to potential debt bondage, and wage withholding.

The Business & Human Rights Resource Centre invited Zijing Mining and Linglong Tire to respond to the allegations made in the report. Zijing Mining denies the allegation. See Zijing's response below. Linglong Tire did not respond.
