More foreigners like Thornhill are tapping the online gold mine either through cross-border e-commerce or as purchasing agents who buy products made in China and sell them in their home countries.

A Rwandan who studied at Jinhua Polytechnic and goes by the Chinese name An Ping registered a company in China in May — Zhonglu International Trading Co — to smooth international business transactions with Africa.

The 29-year-old started his business with four Rwandan partners last year after studying computer science for four years in Jinhua, Zhejiang province.

"When I came to China in 2014, I found that goods here are high quality and cheap. Inspired by my interest in business, I came up with the idea of selling Chinese goods to people in Africa," he said.

His story went viral online recently because of the fortune he made taking advantage of the low prices of Singles Day to lure purchasers in his home country to place orders in advance.

An told Zhejiang Daily that he is adept at using e-commerce and social media platforms to facilitate his business. He buys samples from China's e-commerce platforms such as Taobao and displays them in a shop in Kigali, Rwanda. Then he makes bulk purchases of those items that are most popular with people there.

In the beginning, most of his customers were family members and friends, but now he is helping more than 10,000 people from African countries — Rwanda, Uganda and the Democratic Republic of Congo — to buy Chinese goods.

"Bags, shoes, mobile phones, Chinese books and tea made in China are among the items that sell best in Africa," said An, who spends around 30,000 yuan per week to purchase items for his friends in Rwanda.

Things made in China are gaining more international recognition thanks to its fast-growing e-commerce and international trade.

There's a public group on Facebook called "The Lao Gan Ma Appreciation Society" for global connoisseurs of Lao Gan Ma chili sauce from Guizhou province. The group has more than 2,900 members worldwide, and many have shared pictures of Western food seasoned with the Chinese sauce.
