Kingdom of Funan
Helen Wang points out that although these coins were found in China, they were deposited there in the twentieth century, not in ancient times, and therefore do not shed light on historic contacts between China and Rome. Roman golden medallions made during the reign of Antoninus Pius and quite possibly his successor Marcus Aurelius have been found at Óc Eo in southern Vietnam, which was then part of the Kingdom of Funan bordering the Chinese province of Jiaozhi in northern Vietnam. Given the archaeological finds of Mediterranean artefacts made by Louis Malleret in the 1940s, Óc Eo may have been the same site as the port city of Kattigara described by Ptolemy in his "Geography" (c. 150 CE), although Ferdinand von Richthofen had previously believed it was closer to Hanoi.
