title: Is Firebase Cloud Messaging supported in China?
body: <p>I seen a lot of post saying China banned majority of google's services, and there are also posts that say GCM does not work in China. Since Firebase is owned by Google, does FCM work in China (more specifically, FCM for Android)?</p>
  
  <p>Does Firebase/Google has a list of countries that don't support its services?</p>
