"I am truly happy to do business here and no longer need to worry that my products can not be sold with the new sales channel offered by e-commerce," said Xu Fuqiang, a head of a e-commerce company selling local sweet potato and sea duck eggs in the public service center.

"I can feel the strong e-business climate here. It not only brings good local and Vietnamese goods here, but also innovative and entrepreneurial talents," Xu added.

Dongxing is well placed to develop cross-border e-business due to its proximity to Vietnam and the available national policy that Chinese living in the border area can buy up to 8,000 yuan ($1,150) of Vietnamese goods every day without paying tariffs, which has resulted in mushrooming border transactions.
