In mid-April 2022, a Chinese mine manager was tried and convicted in Rwanda for abusing some of his workers. In this case, the court in Karongi, Rwanda, sentenced him to 20 years in prison for mistreating some of his employees. The Chinese embassy in Kigali reacted to the conviction, citing respect for the laws of Rwanda, but also for those that protect Chinese nationals.

Sometime after the horrific actions of Sun Shujun, the mine manager for the Chinese company Ali Group Holding was tried and convicted for the acts of violence and torture on Rwandans that he is accused of since August 2021. At the time, it was a video massively shared on social networks, which aroused the suspicions of the country's authorities.  In the video, Sun Shujun, a Chinese man, could be seen whipping a Rwandan man lying on the ground with his hands tied to a wooden pole on the outskirts of a cassiterite mine in the Rutsiro district, near Lake Kivu in western Rwanda.

After his arrest, an investigation was opened in this context and four victims were heard by the courts. The investigation revealed that the manager was trying to punish his employees, whom he accused of stealing minerals. In the end, Sun Shujun was sentenced to 20 years in prison by the Karongi court for administering corporal punishment to workers with malicious intent.  The Chinese Embassy in Kigali issued a statement after the verdict, asking Chinese companies and citizens to respect the laws of Rwanda and calling on the Rwandan authorities to protect the rights of Chinese citizens living or visiting Rwanda.
