The story is crazy. There would be NO cost savings.
Yea a Banned Religious group is going to start or buy a mining company in China to get some rocks cheep.
No problems with the Chinese government, you just bribe them to get what you want.
No problem getting skilled labor to run a mining company. We get the 32 underground JWs to work there from all over the country. And they can have Morning Text, and WT studies at lunch break.
And saying they are going to China for High Quality granite? :) Interesting little article about that - http://www.ehow.com/info_12183280_chinese-granite-problems.html
