Hungary has launched an investigation into a major investment by Chinese automaker BYD.

The probe follows the resignation of former Foreign Minister Péter Szijjártó. Szijjártó negotiated the deal before accepting an executive position at BYD, triggering conflict of interest allegations.

Investigators will scrutinize government subsidies, tax breaks, and other benefits facilitated by Szijjártó during his tenure. Prime Minister Péter Magyar confirmed that all state commitments and decisions regarding the investment will be examined.

The investigation creates uncertainty for a key manufacturing hub intended to drive BYD's expansion into the European market.
