The Covid-19 impact on high-value, Asia-based electronics supply chains is deepening. Apple supplier Pegatron suspended operations at a factory outside the Taiwanese capital of Taipei, adding to concerns over outbreaks that have locked down critical business in China. The WSJ’s Joyu Wang and Jonathan Cheng report that the shutdown followed the discovery of 694 Covid cases at the Taoyuan plant, and after Pegatron had already halted production in Shanghai and nearby Kunshan in eastern China. Apple supplier Foxconn has also suspended production at two of its sites in the Kunshan area, the South China Morning Post reported. The outbreak in Taiwan may raise alarms in supply chains, but authorities there have been less strict with lockdowns than Beijing. In Shanghai, container ships are skipping China's busiest port as Covid-related lockdowns have slashed the movement of cargo and shipping lines are saying they won't handle perishable cargo bound for the city.
