UnionPay International (UPI) and National ITMX (NITMX) have partnered to integrate China’s UnionPay payment system with Thailand’s PromptPay.
The initial phase of this collaboration will allow Chinese tourists to utilise the UnionPay app, specifically the YunShanFu app, to pay via PromptPay QR codes at Thai merchants.
This will mirror the payment experience they have in China.
Subsequently, Thai tourists will be able to use UnionPay QR codes for payments within China.
The agreement, formalised through a signing ceremony attended by financial sector officials from both nations, seeks to streamline digital payment for travelers between China and Thailand.
This partnership will extend the use of the YunShanFu app across popular Thai tourist destinations like Bangkok, Phuket, and Chiang Mai, enabling users to scan PromptPay QR codes as they do domestically.
NITMX is also actively working with other Chinese payment providers to further enhance cross-border payment capabilities.

Larry Wang, CEO, UnionPay International said,
“We are happy to collaborate with NITMX, the leading payment infrastructure provider in Thailand, to provide enhanced QR Code payment service. This partnership allows cardholders with UnionPay enabled wallets and UnionPay App to scan PromptPay QR codes conveniently and securely at all PromptPay acceptance points.
Expanding our QR Code payment network globally remains a key priority for us, and this initiative strengthens our commitment to providing seamless payment experiences.”

Chatchai Dusadenoad, Managing Director, National ITMX Company Limited said,
“As Thailand’s leading payment infrastructure provider, National ITMX plays a crucial role in driving interoperability and cross-border payment innovation.
Our collaboration with UnionPay strengthens Thailand’s digital payment ecosystem by enhancing the reach and usability of PromptPay QR Code, ensuring seamless, secure, and convenient cashless transactions for visitors from China and beyond.”
