Primary iPhone assembler Foxconn has invested RMB 1 billion ($140 million) into its facility in Taiyuan, in northern China’s Shanxi province, according to a stock filing released last Friday. The firm claimed that it was a long-term investment, with the move coming against the backdrop of significant disruption to Foxconn’s operations in Zhengzhou. The Taiyuan plant started production in 2004 and is one of the company’s six main facilities in addition to those in Shenzhen, Zhengzhou, Chengdu, Kunshan, and Yantai. The Taiyuan facility, which produces smartphone components and assembles and repairs electronics, is the largest foreign company-invested project in Shanxi province, according to the firm’s website. Apple’s latest suppliers and production locations list for 2021 states that at least one Apple product is made in Foxconn’s facilities in Shanxi; in addition to the Taiyuan plant, the company operates a second facility in the province in Jincheng. Last month, Foxconn was hit by Covid curbs and worker unrest at its Zhengzhou facility, the largest iPhone 14 Pro model assembly line in the world. Analyst Kuo-Ming Chi said the facility’s production capacity utilization was down to just 20% in November, which has led to longer delivery times for the iPhone 14 Pro and Pro Max. [SCMP]
