While WhatsApp continues to be the world’s leading messaging app with over 450 million active users, its rival, WeChat, isn’t too far behind.

Tencent released its latest earnings report this week, indicating that the combined monthly active users between the domestic WeChat app and its Chinese counterpart Weixin have reached 355 million active users by the end of 2013. That’s a 121 percent year-on-year increase, and also a six percent rise from quarter-on-quarter.

While Tencent didn’t provide a breakdown of where users were active depending on region, it did report that it doubled its international reach to 100 million users within a three-month span last year. For good measure, it also passed 100 million downloads through Google Play earlier this year.

No doubt those numbers will continue to rise, making it an even closer race between WeChat and WhatsApp.
