Sept 20 (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.
