The pattern was similar in Tokyo, where the Nikkei slid 1.1 percent against a spiking yen.
Masayuki Kubota, chief strategist at Rakuten Securities, said in a commentary that exchange rates have been affected frequently by political factors including Trump's comments.
And "if US President Trump makes comments criticizing a cheaper yen, the yen's depreciation may halt," Kubota said.
