Shein's retreat from Vietnam is now part of a wider supply-chain shift back to China as U.S. trade policy changes erode Southeast Asia's tariff edge and companies put more weight on speed, quality control and total manufacturing costs. Reuters reported that Shein has cut its leased logistics footprint near Ho Chi Minh City to 6 hectares from an originally planned 15 hectares, while local teams have undergone major layoffs, with some reduced to a quarter of their former size. The company is simultaneously committing more than 10 billion yuan, or about $1.5 billion, to a smart supply-chain system in Guangdong. The broader reversal extends beyond fast fashion. QIMA data showed China's share of inspection and audit business volume from North American clients rebounded to 35% in the second quarter of 2026, the highest in six quarters, while Southeast Asia's share fell back to levels seen before 2025. In Europe, June inspection demand in China rose 10% year-over-year as demand in Southeast Asia fell 5%. Companies including Genimex Group, Steve Madden and Alliance Consumer Group have confirmed they are increasing procurement from China, with Genimex saying some orders have moved back from Vietnam to factories in Zhejiang and Guangdong despite Vietnam's lower unit prices. Executives and suppliers say the main issue is not just tariffs but the hidden costs of offshore production. Rick Helfenbein, former CEO of the American Apparel & Footwear Association, said Vietnam's lower labor costs are offset by weaker supply-chain responsiveness and parts availability, a particular problem for fast fashion. A manager at Ningbo Bright Electric Appliance said export orders rose 15% year-over-year in the first half of 2026 as some clients returned from Vietnam, citing China's supply-chain density and logistics efficiency. Reuters also reported that Apple is seeking to introduce DRAM chips from ChangXin Memory Technologies into its iPhone supply chain to reduce costs, a sign that China's manufacturing ecosystem is regaining appeal across sectors.
