BEIJING — China will strengthen its fast-growing postal industry, an official said on the 48th World Post Day on Oct 9.

The industry, mainly postal and courier services, has seen revenue increase 2.7 times since 2012, and the courier sector has been the world’s largest in terms of delivery volume for three years, said Ma Junsheng, head of the State Post Bureau (SPB).

However, the industry is still facing problems in many fields, including delivery channel safety, vehicles and employee interests, Ma said.

To make the industry stronger, the bureau expects postal and courier companies to expand personalized, professional and one-stop services, Ma said.

SPB will encourage companies to become comprehensive logistical operators and increase their presence overseas, he added.

It will also support state-owned enterprises in railway and civil aviation sectors to join the delivery market to integrate the postal industry with the transportation network, Ma said.

In 2016, delivery volume of China’s courier sector accounted for more than 40 percent of the world’s total with 60 percent of world delivery volume growth.
