Colombian authorities are investigating accusations of bribery against executives from a Chinese state-owned contractor overseeing the construction of Bogota’s metro—South America’s largest infrastructure project. Semana magazine published an investigation revealing a video purportedly showing an executive accepting cash from a local subcontractor. Prosecutors are examining claims that the payments were demanded in exchange for releasing funds owed for completed work. The construction consortium denies any misconduct, asserting the money represented a pre-arranged retention payment. The allegations raise concerns about transparency and ethical practices within the multi-billion dollar project. The investigation is ongoing, with potential implications for the future of the metro’s development and international relations.
