Stop Egress from Americas to China

I've started a simple Tomcat web server in Google Cloud Platform, the Previous month I was charged for a service called 'Compute Engine Network Internet Egress from Americas to China: 2636.552 Gibibyte' and for the service 'Compute Engine Network Internet Egress from Americas to Australia'.

Is there a way to completely ignore these connections or have them blocked in such a way that they will not eat up bandwidth?
