what do christians say about chinese people

[xxThe_Lebowskixx]

Don't Christians think its strange that God choose not to spread his word to the entire human population?

does this suggest that Christianity is actually a man made invention and thus only exists in region it was invented?

Also, if a Christian has a Chinese friend, isn't it his duty to this person to do absolutely everything he can, including physical abuse and torture to convince the Chinese guy to save his soul and believe in Jesus?
