Well, the Romans knew of 'Seres', where the silk they imported in massive amts came from. Though they got most details wrong (incl how silk was produced). It was the Persians' fault - they're acting as middlemen betw China and Rome and growing rich on it.Originally posted by MCdread
Both China and Rome for instance, knew about each other, or better said, knew about the existance of the other. I once read a book where it said that there exist chinese records of at least to roman embassies to China. However the author thought that they were probably indian merchants trying to get some advantadge of the name Rome. And the name of the roman emperor at the time seems similar to the one that is preserved in the chinese records. I do'n have the details here, but I think it was during the ruling of the antonines in Rome.
And there's allways the Silk Rout.
But, the romans had contacts with India, and there were roman merchants living there, so...

The Chinese knew of a powerful far western kingdom they called Ta-Ch'in, west of Persia. Few details though. It was probably Roman Syria though, not Rome itself.
As for that Roman embassy, there was such an entry in Chinese records of an embassy received fr Ta-Ch'in, but they were probably Roman merchants, rather than official representatives, eager to do business thru the tribute system. On the Chinese side, the Chinese sent out an envoy fr Chinese-rule Turkestan during the Eastern Han (1st century AD). The envoy managed to get to the shore of a western sea (prob. the Persian Gulf), before turning back due to rumors by locals (prob. Persians

Roman coins had been unearthed in Cambodia, which was an important trading point betw China and India.
Also the Chinese and the West missed each other by one or two generations in Bactria, Central Asia. Alexander the Great's armies penetrated into the region, and the Greeks stayed, even after the Successor Wars began, setting up a few kingdoms there. One or two generations after the last Greek kingdom in the area was grinded into dust, the first Han Chinese armies penetrated into the region, where they found the unique Graeco-Indian sculpture form (something like that) and this influence travelled back to China thru the Silk Road.
