Why didn't Arab Muslims conquer and islaminize China during the medieval age?

The Great Wall of China kept them out. Throughout history, Muslims have tried and tried to take over other lands but have NEVER won. They need to just stay put, in their own Muslim country, make the best of it and leave everyone else alone.

Maybe it's because of the great wall of China. it kept out the invading forces to some degree

Islam only became to be in middle 5th century out of middle east. placing China away from any possible invasion by the Islamic Empires,

Arabs conquered China religiously.

Cause your are an idiot

Those Arabs only got as far as Persia with their caliphate before it the Mongols destroyed it.

All the invaders of China have either been assimilated or left! China has been invaded more times then history records. Starting (according to the latest information) Egyptians before the common era.

The two routes of conquest from the middle east (excluding the sea routes) just are not compatible with camels! That is a lot of land to cover and to maintain a line of communication. Often by the time an invading army could get to China it would no longer contain members of the starting force.

While several invasions have taken place from bordering locations into Europe- the reverse just has not been successful. The Mongrels and the Huns were pretty autonomous fighting units that did not maintain communications with the "Home land" (for want of a better term).

Consider Alexander the Great who got bogged down in India. It is a logistics nightmare!

Too large and too far away.

Why didn't European Christians conquer and Christianize China during the Medieval period?
