大秦景教流行中国碑
The first recorded Christian mission to China arrived in the Chinese capital Chang'an in 635, during Ishoʿyahb's reign. The mission, whose history was recorded on the famous Nestorian Stele, erected in Chang'an in 781, was led by a Nestorian monk with the Chinese name A-lo-pen. It is possible, but by no means certain, that Ishoʿyahb was behind this initiative.
