China's export growth unexpectedly accelerated in September, as still solid global demand offset some of the pressures on factories from power shortages, supply bottlenecks and a resurgence of domestic COVID-19 cases. The world's second-largest economy has staged an impressive rebound from the pandemic but there are signs the recovery is losing steam. Resilient exports could provide a buffer against growing headwinds including weakening factory activity, persistently soft consumption and a slowing property sector. Outbound shipments in September jumped 28.1% from a year earlier, up from a 25.6% gain in August. Analysts polled by Reuters had forecast growth would ease to 21%.
