Silkroad connected asia to europe from 200BCE to 200CE, gladiators were at their peak around 65-50BCE, and ancient Korea was in its most contentious 3 kingdom period/proto 3 kingdoms period at around 60-40BCE... and also during the Han dynasty (206BC to 220AD) slavery was a large trade, but limited and supervised by the government (for nobles mostly)
SO the historical timelines line up, and although unusual, not impossible, and all that from a 10min google search
