On May 7, the 3,016th train from Sino-Asia Railway left Qingdao for Kazakhstan, a trip that takes only 10 days instead of the 30 days required for sea transportation. Now Qingdao central station has five international railway lines, including Sino-Asia, Sino-Europe, Sino-Korea, Sino-Mongolia and ASEAN Express.

The goods transported on the Sino-Asia Railway are mainly two types -- international transfer products and Shandong local products, said Wang Jun, director of the Jiaozhou Bay International Logistics Park management committee.

The international transfer products are mainly small household appliances, auto parts from Japan and South Korea, and agricultural products from the US and Southeast Asia. The local products are mainly rubber, tires and textiles, Wang said.

At the same time, the Qingdao Jiaodong International Airport under construction is expected to open 186 airline routes in 2019, as the portal of Japan and South Korea and pivot of the Bohai region.
