As Google services are blocked in china will parse notifications work there. As i had heard Parse is using the GCM services only for sending the push notifications it will not work in china. Is it correct ?
They won't work. I know people who bought a Galaxy in China and didn't even have the Google Play Store installed. They couldn't even download the Play Store. So the GCM are blocked, thus the Pushes won't work.
But there are alternatives out there! :-)
