According to Reuters, Trump issued the executive order just 15 days before his successor, Joe Biden, is set to be inaugurated.
It bans transactions in the US via major Chinese Big Tech wallet providers including Ant Group and Tencent.
President-elect Biden will inherit a long history of tensions between the US and China, stoked in recent years by the Trump administration.
Last year, Tencent’s WeChat was targeted by an executive order focused on Chinese social media apps.
