China has executed 11 members of a mafia family for killing 14 people and running a crime syndicate worth more than $1bn, authorities said. In September, the Ming family members, including Ming Guoping, Ming Zhenzhen, Zhou Weichang, Wu Hongming and Luao Jianzhang, were sentenced to death for a host of crimes. They had been found guilty of killing 14 Chinese citizens, as well as illegal detention and fraud. Authorities in the region face growing international pressure from China, the US and other nations to address the proliferation of criminal activity. In recent years, China executed more people than any other country - sometimes more than every other country in the world combined.
