Express delivery companies in northern China are reporting damaged parcels due to flooding caused by heavy rains.

The rains have caused widespread flooding in the region, including in Beijing, Tianjin and Hebei province.

STO Express, a major parcel delivery company in China, said it has made emergency plans in advance to ensure that parcels can be safely stored. However, the company said some parcels have been damaged due to the extreme weather.

YTO Express, another major parcel delivery company, said some of its sites and vehicles have been flooded. The company said it is still counting the loss and will assist local bureaus and sites to explain to customers.

China Post Group's Beijing Branch said mails and parcels in some flood-hit towns in Mentougou, Beijing, have been stored properly. The company said anti-flood supplies such as sand bags have been placed at sites on lower altitude.

As of Thursday, parcel delivery network has resumed operation in most areas in Beijing, Tianjin and Hebei province. However, some parcels have been delayed. The companies said they are making efforts to solve the problem and deliver the parcels to customers as soon as possible.
