Former Federal Reserve Chairman Ben Bernanke said that China’s economic slowdown should not worry markets as there was no risk of a hard landing, and emphasized that a move to raise U.S. rates should be viewed as a positive sign for the world’s largest economy. Bernanke, who participated in an open interview at a private-sector forum in Seoul on Wednesday, said the expected U.S. rate hike would be “anticlimactic” when it happens and that there would only be minor negative impact on South Korea.
