1900 years ago is not so long. Roman times. Trade goods floated back and forth across the deserts, mountains, and steppes, and the routes were well established. While most of the trade was presumably staged, at least a few adventurous individuals would have made the entire journey.

Have we found any graves of Asian travellers of the period in the West -- aside from remains of the warring steppes tribes, of course, who were rather spectacularly present?

They weren't travellers, they were residents.

"Asian" is a vague term. You mean Oriental. Well, after the Chinese were converted to Buddhism by Indian missionaries sent by the Indian Emperor Asoka, Hsuien -Tsang (?) a Chinese traveller did travel to the lands west of the Gobi desert. We're not sure how far west he went though -- probably up to Parthia, maybe further. However, prior to this there was trade from China as early as Phoenician times (and THAT is ancient!)
