鼎盛的唐王朝,东面和新罗、日本诸国有着友好的往来,西面和大食、拂菻有着友好的往来,西南面和五天竺以及师子等国有着友好的往来。安史之乱以后,吐蕃占据了河西走廊和河湟地区, 唐西面的陆路交通几乎断绝,但是南海的交通却特别发展起来。 The prosperous Tang dynasty, the east, the Silla and Japan all have friendly exchanges. The west and the great food have a friendly contact with the motherland and the friendly relations between the southwest and the five-day Zhu and the Shizi. After the Anhsan rebellion, Tubo occupied the Hexi Corridor and the Hehuang area. The road traffic west of the Tang area was almost cut off. However, traffic in the South China Sea was especially developed.
