Facebook arguably attempts to. The markets are different, and people prefer separate apps, rather than using facebook apps in the facebook app, but facebook still does the core part of all the different things.
People outside of mainland china (including Hong Kong and Taiwan) still prefer separate apps, and WeChat has been unable to acquire any significant marketshare outside of mainland Chinese users. Heck, even newly opened Myanmar is already dominated by google and Facebook.
The GFW has severely crippled the web, coupled with the lack of card usage, created a situation that made wechat work for mainland china and can't really be replicated anywhere else.

Wechat simply has never had to compete with worldwide services. We can say it beat Facebook and google, but that would be stupid because both of those are blocked and have been for a long time. The fact that Chinese internet services are spurned in China's own backyard is telling.
