HONG KONG (AP) — China’s exports grew 2.5% in March from a year ago, significantly slowing from the previous two months as uncertainties rose from the Iran war and its impact on energy prices and global demand. The March export data released by China’s customs agency Tuesday missed analysts’ estimates and was sharply down from the 21.8% export growth recorded for January and February. Imports last month surged 27.8%, up from the 19.8% year-on-year increase in the first two months of this year.
