China announced that the first outbound international rail-sea freight train from China's Yangtze River to Indo-China Peninsula left Guoyuan Port in southwest China's Chongqing Municipality for Myanmar's Yangon on April 7.

Chinese state media said the new route from the inland port along the Yangtze River to Yangon also links Chongqing with the Indian Ocean — and comes under the framework of the New International Land-Sea Trade Corridor, a trade and logistics passage jointly built by western Chinese provinces and Singapore.

"The new transport service offers another quick passage from western China to the Indian Ocean, said Wang Yupei, chairman of the corridor operator," Xinhua said in a report.

It noted that compared with traditional logistics routes that extend to eastern coastal cities via the Yangtze River and then to the sea, the new route can save over 20 days on the way.

Guoyuan Port in Chongqing is the largest port on the upper reaches of the Yangtze River and a key point connecting the Yangtze River Economic Belt and regions along the Belt and Road.

The report noted that by the end of 2021, there will be 315 ports in 107 countries and regions worldwide that could be reached via the New International Land-Sea Trade Corridor.
