Google is continuing to test new strategies in China after the U.S. search giant released its first mini program for WeChat, the country’s hugely popular messaging app.

WeChat is used by hundreds of millions of Chinese people daily for services that stretch beyond chat to include mobile payments, bill paying, food delivery and more. Tencent, the company that operates WeChat, added mini programs last year and they effectively operate like apps that are attached to the service. That means that users bypass Google Play or Apple’s App Store and install them from WeChat.
