Hungary's Sweeping BYD Szeged Probe Uncovers €175 Million in Secret Subsidies Amid 29 Criminal Cases and Forced Labor Scandal

The political, labor, and industrial crisis surrounding Chinese electric vehicle giant BYD's €4 billion factory in Szeged, Hungary, has intensified dramatically following a major government transition and a high-profile conflict-of-interest scandal.

Hungary's new government, led by Prime Minister Peter Magyar (who assumed power in May 2026), launched a sweeping investigation on Monday, July 20, 2026, into the BYD Szeged investment. The probe was triggered by a public outcry over the appointment of former Hungarian Foreign Minister Péter Szijjártó to an executive role at BYD (executive in charge of external relations and new business development) immediately after resigning from parliament. Szijjártó had negotiated the massive BYD factory deal while in office.

PM Peter Magyar vowed to thoroughly investigate the deal:

"We will examine every decision, every negotiation and every state commitment of Peter Szijjarto that was connected to the BYD Hungary investment... [We will expose] every subsidy, tax break, fast-tracked permit, environmental exemption and publicly funded investment."

The investigation immediately translated into action. On Tuesday, July 21, 2026, Hungarian inspectors arrived at the BYD Szeged factory site to conduct snap audits of workers' papers, focusing on residency permits, social security cards, contracts, and other legal documents. This follows previous allegations of forced labor and labor law violations by subcontractors building the plant.

Similar snap audits were carried out at a Chinese battery supply chain company on Monday, July 20, and at another Chinese firm in Debrecen, spreading anxiety among Chinese executives that the BYD probe could impact all Chinese investments in Hungary.

In addition to labor and subsidy compliance, Magyar announced an investigation into Szijjártó's dealings with Russia, following reports that he had briefed Moscow on EU deliberations while serving as foreign minister.

This domestic crackdown by Hungary's new government occurs as the European Commission continues its own preliminary foreign subsidy probe into the Szeged plant, aiming to close loopholes and protect the EU market from subsidized Chinese EV and plug-in hybrid (PHEV) imports.
