(Reuters) - Vietnamese electric-vehicle maker VinFast reported a deeper second-quarter loss on Friday, driven by rising costs linked to its ambitious Asia expansion, although its revenue remained on a rising trend, its exchange filing showed.

VinFast, which started delivering cars in California last year, reported a gross loss of $224 million in the April-to-June period, compared with $151 million in the previous quarter.
