Extending of China visa in Jordan (Amman)

Hello my name is Mofeed Im from Iraq ( Kurdistan ). I ownes Netherlands Nationality. My brother got car accident in 2007. I want to bring him to China for medical tretment. I got chinesse visa's three months ago, but we couldn't travel becaus of bad condition of my brother. the visa is expierd in 29 sep. 2011. I tried to extend the visa's for my brother and three other hour family members. but becaus of the politic situation in Syria we couldn't extend the visa's. the old visa's where issued in Syria ( Damascus ).

Is there posibility to extend the visa's in Jordan ( Amman )?
I can travel to Jordan, but the rest of my family members owunes just Iraqi nationality. and they need a visa to travel to Jordan. and my brother can't travel because of his accident and his bad condition.
Is that possible that I bring all passports to extend the visa's in Amman?
I have a letter with invatation of Hospital in China.

My best regards,

Mofeed Agah
