News yesterday (December 12, 2014): the WeChat team posted an announcement on the WeChat Official Platform titled “Domains shared in Moments require ICP filing,” stating that starting today, web domains shared in WeChat Moments require ICP filing — meaning content in WeChat must all be moved to domestic servers. 
The announcement reads as follows:
First, a bit about ICP filing. The “Internet Information Service Management Measures” state that internet information services are divided into commercial and non-commercial categories. The state implements a licensing system for commercial internet information services, and a filing system for non-commercial ones. The “Non-commercial Internet Information Service Filing Management Measures” state that providing non-commercial internet information services within the territory of the People’s Republic of China requires filing formalities in accordance with the law. Without filing, you may not provide non-commercial internet information services within the territory of the PRC.
How to do ICP filing?
First, your server must be in China; servers outside China cannot be filed. Filing is not submitted by the individual — it is submitted by your server service provider to the local communications administration. You need a copy of your ID card, a completed verification form, and a photo of the site responsible person taken against a designated backdrop for verification. Even with complete materials, it takes 20 working days to complete the filing.
Does ICP filing cost money?
ICP filing is the obligation of the server access provider, who assists with filing for free — provided you use a domestic server; overseas servers cannot be filed.
Are there benefits?
There are benefits: domestic servers are fast, and filing also protects visitors’ rights. Once a site publishes inappropriate content, the site responsible person can be found immediately. Other questions:
