China's e-commerce export boom is losing momentum as the Iran war drives up jet fuel costs and dampens demand from lower-income consumers in the West, putting profits at risk for major retailers including Temu, Shein and AliExpress.

The business models, based ⁠on flying $5 dresses from Chinese factories to shoppers around the world, were already under pressure after U.S. President Donald Trump introduced tariffs and axed customs waivers on low-value parcels last year.
