REUTERS/Greg Baker/PoolChina said on Tuesday it was opposed to any country using its own laws to carry out “long arm jurisdiction”, after the United States sanctioned a Chinese industrial machinery wholesaler tied to North Korea’s nuclear programme. The US Treasury said it was sanctioning Dandong Hongxiang Industrial Development along with its executives Zhou Jianshu, Hong Jinhua, Luo Chuanxu and its owner Ma Xiaohong under US regulations targeting proliferators of weapons of mass destruction. It accused the firm of acting on behalf of North Korea’s Korea Kwangson Banking Corp (KKBC), which has been under US and UN sanctions for supporting proliferation of such weapons. Asked about the move, Chinese Foreign Ministry spokesman Geng Shuang said China was committed to upholding United Nations Security Council resolutions against North Korea, which mandate tough sanctions for its nuclear and missile tests. Any person or company found in breach of the rules would be punished and if necessary China would cooperate with other countries on this on the basis of mutual respect and equality, Geng told a daily news briefing. “I want to stress that we oppose any country enacting so-called long arm jurisdiction, using its own domestic laws against a Chinese entity or individual,” he added. “We have already communicated this position to the US side,” Geng said, without elaborating.
