A Vietnam court Friday ordered ride-hailing app Grab to pay a cab company more than US$200,000 for losses incurred due to competition – a judgement blasted by the firm as "a giant step backwards" for the country's tech community.The Singapore-based app, which launched in Vietnam in 2013, has been embroiled in a lawsuit with Vinasun, a major taxi provider in the south of the country, since May 2017.
