Vietnam's automaker VinFast on Friday said it will push back its plan to start operations of its electric vehicles factory in the United States until 2025, citing a procedural delay. The unit of conglomerate Vingroup JSC flagged the plan to build a USD 4 billion EV factory in North Carolina's Chatham County on 712 hectares (1759 acres) of land in March last year, with commissioning targeted for July 2024.
