Meanwhile, coffee imported from Vietnam and Laos goes from Chongqing to the European market via the Chonqing-Xinjiang-Europe international train route.

Launched in Chongqing, the 11,179-km link passes through Xi'an, Lanzhou, Urumqi and the Alataw Pass, where it enters Kazakhstan, before continuing through Russia, Belarus and Poland, finally reaching Duisburg, Germany.
