11 individuals convicted of intentional homicide, fraud, and other offenses tied to a transnational fraud scheme were executed after the nation’s highest court approved their death sentences, officials said Thursday.

The notice was published on the website of the Supreme People’s Procuratorate, China’s top state organ overseeing criminal prosecution and supervision.

The executions followed a ruling and execution order from the Supreme People’s Court, which affirmed lower-court judgments against members of the so-called Ming family criminal syndicate.

They stood accused of operating large-scale fraud and gambling enterprises from northern Myanmar that handled more than 10 billion yuan, about $1.4 billion.

Authorities said the syndicate conspired with criminal groups led by “financial backers” to manage illegal casinos, narcotics trafficking, and prostitution activities.

“The Ming family criminal group also colluded with the online fraud criminal group of Wu Hongming and others to deliberately kill, intentionally injure, and illegally detain people involved in fraud, resulting in the death of 14 Chinese citizens and injuries to many others,” the Supreme People’s Procuratorate said.

Ming Guoping, Ming Zhenzhen, Zhou Weichang, Wu Hongming, Wu Senlong, and Fu Yubin were among those sentenced to death in September by the Wenzhou Intermediate People’s Court of Zhejiang Province.

The Zhejiang Higher People’s Court on Nov. 25 rejected the appeal, upheld the original verdict and submitted the case to the Supreme People’s Court for mandatory review.

Authorities said the prisoners were allowed to meet with close relatives before the executions were carried out.
