On Tuesday, Chinese smart vehicle supplier Shanghai PATEO stated along with General Motors Co’s local venture with SAIC Motor Corp it has filed a joint complaint against Chinese tech giant Tencent to China’s market regulator.

In a statement, PATEO said Tencent abused its dominant messaging app’s market position to restrict sales of its products which have functions controlled via WeChat. Further, since August 2020, Tencent has been asking car companies to stop using PATEO’s Internet of Vehicles products.

Neither GM, SAIC’s joint venture SAIC-GM-Wuling nor Tencent immediately responded to requests for comments.

Ever since Jack Ma publicly called for improving China’s financial regulations, Beijing has launched a probe into e-commerce giant Alibaba and has doled out punishments to Alibaba-backed and Tencent-backed firms.
