The Appeal Court on Friday upheld the murder convictions of two Chinese men, sentenced to 13 years for the 2011 stabbing death of a friend.

Kor Yinkouy and Vorng Fangphin, both from China, may further appeal their case to the Supreme Court within one month, said Judge Somrith Sophal, who presided over the case.

The two men were convicted in Phnom Penh Municipal Court last July of stabbing Jiang Yakong, also from China, to death in Russey Keo district’s Prek Leap commune on December 13, 2011, Sophal said.

On Friday, Fangphin admitted to stabbing Yakong to death, but insisted he was not at fault.

The three men had been drinking together that night and when an argument broke out, Yakong pulled a knife and stabbed Yinkouy. When Fangphin intervened, Yakong kicked him, he said in court.

Fangphin then got ahold of the knife and stabbed him to death, he claimed.
