Uber and Alipay teamed up earlier this year to offer Chinese yuan payment options for Uber rides in Hong Kong, Macao and Taiwan.
The option has been expanded to more than 400 cities in 68 countries and regions in which Uber operates, state-run Xinhua news agency reported.
China has emerged as the world's biggest source of outbound travellers. Last year over 120 million Chinese tourists travelled out of China. But most of them go through group tour packages.
Uber also wants to tap China's travel boom by encouraging Chinese tourists to book rides using its service in foreign countries.
Previously, Chinese riders had to pay Uber fares in US dollars.
Uber rival Didi said last month that it has allowed Chinese tourists using its mobile app to access ride-hailing services through its partner Lyft in the US, with bills payable through mobile payment services from China's Alibaba and Tencent.
