How did papermaking spread abroad?

Papermaking first spread from China to Korea and Vietnam, and then from Korea to Japan at the end of Sui Dynasty (AD 6 10). It spread westward to Samarkand and even to Baghdad, Damascus, Egypt and Morocco. By the year 1 150, Spain under the Arab rule began to make paper, which was the first paper workshop in Europe. After the Vatican conquered Spain under Islamic rule in A.D. 12 12, the European paper industry developed rapidly, more than 0.000 years after Cai Lun invented papermaking. Until the end of 18, western paper was still almost entirely handmade.
