When a man surnamed Wang in Beijing ordered a car for traveling with friends on zuche.com, a leading car-renting platform in China, he was astonished to be declined.

After trying several times in vain, Wang got angry and filed a complaint with customer service.

Wang was told that his order was refused because of a negative credit record. The customer service representative told him that he would face limits on other platforms for the same reason.

Earlier this year, Wang was put on a credit blacklist by a court in the Haidian area of Beijing because he refused to fulfill his legal obligations arising from a lawsuit four years ago.

Courts sometimes encounter problems with judgment enforcement, especially when individuals or institutions refuse to pay.

Since 2015, the Supreme People's Court (SPC) of China has collaborated with Internet companies, such as Taobao, JD.com and Tencent, to punish credit defaulters.

The SPC started cooperating with Sesame (Zhima) on July 24th, 2015 to share networked information about people who disobey court orders to pay -- a first attempt of its kind.

Sesame prohibits them from using online platforms, including shopping on Taobao, renting a car, buying tourism products such as plane or train tickets, or booking a hotel room.

They are also given a low credit record which is released online to urge them to comply.

After learning about the policy and under huge pressure, Wang voluntarily contacted the lawyer in charge of his case and made payment in accordance with the court order.
