Tencent says it's in contact with Russian authorities over its ban on the use of messaging apps connected to Wechat.

Russia's telecom watchdog announced earlier this week that WeChat is not in compliance with Russia's information laws.

At issue is registration.

Internet-based companies which have links in Russia are required to register with the government.

Tencent says it "had a different understanding" of the issue.

Other social media apps, including Blackberry Messenger, Imo and Line, have also run into similar restrictions in Russia.

WeChat is available in a vast majority of countries around the world.

Tencent says it has around 900-million users worldwide.
