Southwest China's Guizhou Province has exported 1.97 million tonnes of cargo, worth 10.2 billion yuan (about 1.5 billion U.S. dollars), to countries along the Belt and Road since April last year, according to the province's department of commerce Wednesday.

After the Guizhou section of the land-sea freight route opened to traffic in April last year, local products such as white spirit, fertilizers, tires and tea have been popular sellers in foreign markets along the Belt and Road, said the commerce.

On May 20, Guizhou's first supply chain management company was set up to reduce logistics costs along the land-sea freight route and promote trade and cultural exchanges among countries and regions along the Belt and Road.

The land-sea freight route is part of the New International Land-Sea Trade Corridor, a trade and logistics passage jointly built by western Chinese provincial regions and Singapore under the framework of the China-Singapore (Chongqing) Demonstration Initiative on Strategic Connectivity.

By the end of March, the land-sea freight route had seen 901 trips, transporting 440 million U.S. dollars worth of auto parts, construction materials, porcelain, chemical products, grains and frozen goods.

It links 166 ports in 71 countries and regions worldwide.
