Merchants can set up shop in three-to-four weeks rather than the typical 12 months that it takes foreign brands to begin selling in China, JD said.JD will handle the price conversion as well as logistics from U.S. to China. JD has its own logistics arm with a vast network of delivery workers and warehouses which the company sees as a competitive advantage over its rival Alibaba.Shopify and JD will also “collaborate to simplify access and compliance for Chinese brands and merchants looking to reach consumers in Western markets,” they said.Shopify has dipped its toe into the China market before. In 2020, the company began allowing merchants to accept payment via Alipay, one of China’s two popular digital wallets. Alipay is run by Alibaba affiliate Ant Group.But the tie-up with JD is its most significant push yet, as the Chinese e-commerce giant has more than 550 million annual active customers.
