China’s central bank (the People’s Bank of China, or PBOC) issued regulations to supervise “non-financial institutions” that provide payment services. The rules took effect later in 2010 and set a deadline for existing payment firms to apply for a payment business permit. This created a clearer legal framework for fast-growing third-party payments that Alipay and, later, WeChat Pay would build on.
The PBOC’s payment-services rules became effective, meaning payment companies now operated under formal supervision. The measures required payment firms to apply for a permit within a set window or stop providing payment services. This enforcement date marked a major step from informal growth toward regulated expansion.
Alipay and WeChat Pay later relied heavily on QR codes (square, scannable codes) for in-person payments. Research on China’s payments market describes both companies introducing proprietary QR approaches around 2011, which helped low-cost merchant acceptance spread quickly. This set up the later boom in street-level and small-merchant digital payments.
Tencent released Weixin (known internationally as WeChat), initially as a messaging app. Its rapid user growth created a large social network inside one app, which later became a powerful base for adding payments. This “social-first” design would help WeChat Pay expand quickly once payment features arrived.
The PBOC announced its first batch of third-party payment permits for 27 companies, including Alipay and Tenpay (Tencent’s payments business at the time). The permits gave major payment providers clearer legal standing and encouraged wider competition and investment. This milestone helped normalize third-party digital payments in China’s financial system.
Alipay’s smartphone app (often described as a “mobile wallet”) expanded mobile payment use beyond desktop e-commerce toward everyday phone-based transactions. Reporting in later years noted that Alipay’s existing e-payments app had been available since 2009 and was upgraded for more offline-style use cases. These changes helped Alipay become a key tool for mobile-first payments in China.
WeChat introduced WeChat Pay (Weixin Pay), adding a wallet and payment function inside the messaging app. This made it easier for users to move money between people and, later, to merchants without leaving their main social app. The launch set up direct competition with Alipay in mobile payments.
During the 2014 Lunar New Year period, Tencent launched digital “red envelopes” (hongbao) inside WeChat Pay, letting users send money to friends and groups as gifts. The feature tied payments to a familiar cultural practice and made peer-to-peer transfers feel natural inside chats. It became a major adoption driver for WeChat Pay and intensified rivalry with Alipay.
As domestic adoption surged, Alipay began targeting Chinese outbound travelers by signing overseas merchants. Reporting describes Alipay’s early European acceptance in 2015 at a Frankfurt Airport retailer, with expansion to other major shopping destinations afterward. This strategy used tourism to seed cross-border growth without requiring foreign users to switch payment habits immediately.
WeChat connected with Western Union’s WU Connect platform to support cross-border person-to-person money transfers. The partnership focused on enabling international transfers through a familiar social app interface. It was an early step in positioning WeChat’s payments beyond mainland China.
By the mid-2010s, Alipay and WeChat Pay had become the core rails of everyday mobile payments in China, especially through QR-code merchant acceptance. Research organizations described the two platforms together controlling the vast majority of China’s mobile payment segment. This period marks the shift from “online checkout tools” to near-ubiquitous in-store payment methods.
WeChat Pay announced its cross-border payment service had expanded to over 49 countries and regions and supported payments in multiple currencies. The focus remained on serving Chinese travelers abroad by enabling payments without traditional cash exchange at checkout. This milestone reflects WeChat Pay’s transition from a domestic wallet to an international acceptance network.
As Alipay’s and WeChat’s payment ecosystems grew, they drew more attention from regulators and international policymakers, including concerns about data, financial risk, and geopolitical tension. Coverage of Ant Group in 2020 highlighted both the scale of Alipay’s role in daily life and the increasing regulatory and political pressure surrounding its growth. This marks a turning point from rapid expansion toward tighter oversight shaping the next phase beyond 2020.
