A non-stop bus service linking Nanning, capital of south China's Guangxi Zhuang Autonomous Region, with Hanoi, Vietnam's capital, opened on Wednesday.
Prior to the new service, passengers had to change coaches after going through customs checks.
The 381-km direct trip takes 7.5 hours.
It was opened based on a bilateral agreement between China and Vietnam in effect since Feb. 17, which helped remove institutional obstacles on running direct road transport services.
The agreement also allows official vehicles with special permits to be exempted from going through customs routines, which is the first such practice between China and its neighboring countries.
Guangxi, as a gateway for enhancing China's strategic cooperation with members of the Association of Southeast Asian Nations, has 28 roads linking it to Vietnam.
