LANZHOU, March 15 (Xinhua) -- A land-sea trade route now connects Lanzhou, capital of northwest China's Gansu Province, with Bangkok in Thailand.

Twenty-eight carriages of PVC particles with a weight of 720 tonnes left Lanzhou on Friday for Qinzhou Port in south China's Guangxi Zhuang Autonomous Region, where they will be transferred to ships and are expected to arrive in Bangkok on March 25.

"The successful launch of the land-sea trade route is an important step for the opening-up of Lanzhou as well as Gansu Province," said He Jing, deputy director of the Lanzhou New Area Administration Committee.

The Lanzhou-Qinzhou-Bangkok trade route takes advantage of the New International Land-Sea Trade Corridor, a trade and logistics passage jointly built by west China provinces and ASEAN countries under the framework of the China-Singapore (Chongqing) Demonstration Initiative on Strategic Connectivity.

With Chongqing as the transport hub, the corridor uses ports in Guangxi's Beibu Gulf to reach ports in Singapore and other ASEAN countries and links China-Europe freight trains launched from many west China cities before heading for Central Asia, South Asia and Europe.
