Ant Financial, the parent of the Alipay mobile wallet, is extending its partnership deal with the Industrial and Commercial Bank of China. It will allow merchants to accept payment in the Alipay app or the ICBC mobile banking app, without the need for users to replace their QR codes. 

The companies have already piloted the payment features in three major Chinese cities, including Hangzhou, Chongqing and Guangzhou and will expand to additional cities across the country. 

Alibaba Group and Ant Financial originally announced the partnership with ICBC in December and it involves collaboration in payments, e-commerce and fintech services. ICBC, a state-owned bank in China, is the world's largest single bank based on assets. Alipay is the most widely used mobile wallet in the world.
