At a participating shop or restaurant in Vietnam, a visitor from China can open UnionPay, Alipay or Weixin Pay and scan the VietQRGlobal code at the counter. There is no need for the merchant to display a separate code for each platform, or for the visitor to download a Vietnamese payment app.

That simple experience has taken several connections to build. UnionPay went live in December 2025, Alipay followed in April 2026, and Weixin Pay joined in August. Each platform has its own connection to Vietnam's payment infrastructure, with local banking partners helping to process and settle transactions.

The shared piece is the acceptance point, not the payment system. Vietnam is not merging UnionPay, Alipay and Weixin Pay into one system, and it is not launching three separate services at the counter. Merchants display one VietQRGlobal code. Behind it, each app still reaches the merchant through its own connection.

What happened

The latest addition came through an agreement between the National Payment Corporation of Vietnam (NAPAS), BIDV and Weixin Pay. Visitors can pay by scanning VietQRGlobal through Weixin Pay, also known as WeChat Pay, with BIDV providing the clearing and settlement system.

Alipay's connection also runs through NAPAS, with Vietcombank handling settlement directly between Chinese Yuan and Vietnamese Dong. UnionPay was the first of the three Chinese payment platforms to connect.

A shared code does not remove that work. NAPAS connects Vietnam's payment infrastructure to each foreign platform, while the participating banks and payment providers handle the arrangements needed to move money between systems.

The network is also extending beyond China. South Korean visitors can use participating GLN-linked apps at VietQRGlobal merchants. A connection with Singapore began with inbound payments and had become two-way by September, according to NAPAS.

Early usage figures suggest payments from Chinese apps are gaining traction. NAPAS said the number of transactions made by Chinese visitors using Chinese payment apps to scan VietQRGlobal tripled between April and August, while transaction value quadrupled. Those figures cover the combined Chinese payment connections, and cannot isolate the contribution from Weixin Pay, which joined only in August.

What it means

For merchants, the attraction is being able to accept more foreign payment apps without creating a separate checkout process for each one.

A familiar QR code at the counter can serve customers whose payments originate in different overseas systems. The technical work sits behind the transaction, in the connections between NAPAS, the foreign payment platforms and local banking partners.

That could become more valuable as Vietnam receives visitors from more markets. The country can extend the same acceptance point to another incoming payment network, while each new connection still requires its own technical and commercial work. The merchant experience need not change each time.

There may also be a financial incentive. NAPAS expects merchants to pay a discount rate of around 1.5% for VietQRGlobal transactions, compared with 2.4% to 3.0% for international cards issued outside Vietnam. If those rates are reflected in the terms merchants actually receive, the service could offer a cheaper way to accept payments from foreign visitors.

For now, that remains an expected advantage rather than a demonstrated saving across the merchant network. Actual costs will depend on merchant agreements, settlement arrangements and the terms offered by participating providers.

The model also offers visitors a familiar way to pay. They can continue using an app they already have, and the Vietnamese merchant receives the payment through the local acceptance network, even though the transaction starts in a foreign payment system.

The regional ambition is larger than any one Chinese connection.

NAPAS and its partners are building links that could make VietQRGlobal a gateway for payment apps from multiple countries. Meanwhile, in August, NAPAS, BIDV and Weixin Pay said they would continue exploring the reverse flow, which would allow Vietnamese travellers to use domestic banking or wallet apps in China.

What to watch

• Merchant coverage. A shared acceptance point is useful only where visitors can find it. The number and distribution of active acceptance points will show whether it extends beyond selected merchants and tourist areas.

• The actual cost of acceptance. NAPAS's expected 1.5% discount rate looks competitive against the cited international card rates. Merchant contracts and settlement terms will show whether the difference becomes a real saving.

• More countries, not just more apps. The network grows if Vietnam can connect payment systems from additional markets without asking merchants to change the checkout each time.
