Roman Empire
Roman embassy from "Daqin"
Daqin (Present-Day in China)
It is possible that an alleged Roman embassy from "Daqin" that arrived in Eastern Han China in 166 via a Roman maritime route into the South China Sea, landing at Jiaozhou (northern Vietnam) and bearing gifts for the Emperor Huan of Han (r. 146–168), was sent by Marcus Aurelius, or his predecessor Antoninus Pius (the confusion stems from the transliteration of their names as "Andun", Chinese: 安敦).
