Robust overseas demand has underpinned exports and factory output, which have been a bright spot for the world"s third-largest economy over the past months, despite May"s slump which was due to a sharp fall in car production. "As production adjustments at some factories of carmakers are expected to continue from July onward due to the prolonged impact of the chip shortage, there remains a downside risk to car output," said Junpei Fujita, an economists at Mitsubishi UFJ Research and Consulting.
