China’s e-commerce juggernaut Alibaba Group is reigniting a yearslong effort to expand overseas as it seeks to offset a weakened grip on online retail at home. This time, it’s adding artificial intelligence to the mix. Alibaba’s family of generative AI models and new teams focused on AI applications are beginning to support the company’s drive to expand well beyond China, including by helping small sellers overcome language barriers and take on more complex tasks like negotiating refunds, said Zhang Kaifu, head of AI development at Alibaba’s international e-commerce unit.
