BEIJING—China’s economy flashed more warning signs in May as the United States ramped up trade pressure, with industrial output growth unexpectedly slowing to a more than 17-year low and investment cooling, underlining a need for more stimulus.
Hours after the surprisingly weak data, China’s central bank announced 300 billion yuan ($43 billion) in fresh support for smaller banks, though analysts expect more sweeping measures in coming months if the U.S.-Sino trade dispute intensifies.
