A maritime Silk Route opened up between Chinese-controlled Giao Chỉ (centred in modern Vietnam, near Hanoi), probably by the 1st century. It extended, via ports on the coasts of India and Sri Lanka, all the way to Roman-controlled ports in Roman Egypt and the Nabataean territories on the northeastern coast of the Red Sea. The earliest Roman glassware bowl found in China was unearthed from a Western Han tomb in Guangzhou, dated to the early 1st century BCE, indicating that Roman commercial items were being imported through the South China Sea. According to Chinese dynastic histories, it is from this region that the Roman embassies arrived in China, beginning in 166 CE during the reigns of Marcus Aurelius and Emperor Huan of Han. Other Roman glasswares have been found in Eastern-Han-era tombs (25–220 CE) more further inland in Nanjing and Luoyang.
