Possible Backdoor in MiPad-1?

Yesterday, I connected my MiPad to the internet for the first time and noticed a lot of background downloading happening immediately. This is not supposed to be happening since I've disabled automatic update checking and running the latest stable ROM (V7.3.1.0.KXFMIDD) from here. I used the "busybox netstat -at" command to see what's going on and sure enough, found that the MiPad is downloading lots of data from the IP 42.62.94.2 on the xmpp-client port:

Code:

I did a quick google search and found that others have found this and suspected a backdoor too. The WHOIS information is traced to a company called WLWM Communication Tech. co. ltd in Haidian District,Beijing. Can some experts here explain what could be going on here?
