Before the agreement, mainland Chinese travellers using the Uber app overseas needed to connect a dual-currency credit card with their Uber account and were billed for their journeys in US dollars.
Alipay is the online payment service of Ant Financial Services, an affiliate of Chinese e-commerce giant Alibaba.
Alibaba is an investor in both Didi and Lyft, on top of its partnership with Uber.
Uber said its customers had been able to use Alipay for their journeys in mainline China since 2014 and in Hong Kong, Taiwan and Macau since early 2016.
The San Francisco-based company said the cross-border payments arrangement would cover mainland Chinese travellers in 400 cities.
Uber and Alibaba said they intended to expand co-operation in India through Alipay's links with Paytm, which is India's largest mobile payment provider.
Early last year, Ant Financial teamed up with parent company Alibaba to invest more than $500m (Â£341m) in Paytm.

The four companies have formed a strategic partnership in a bid to compete with Uber.
