BOGOTA/SHANGHAI (Reuters) – Colombian authorities detained a vessel operated by China’s largest shipping group for illegally transporting thousands of cannon shells, about 100 tonnes of gunpowder and other materials used to make explosives, the attorney general’s office said. The Da Dan Xia, operated by Cosco Shipping Co Ltd, was headed for Cuba when it was stopped on Saturday in the northern port of Cartagena, on the Caribbean coast, after the materials were detected during an inspection. China’s Foreign Ministry spokeswoman Hua Chunying said the ship was carrying ordinary military supplies to Cuba and was not in violation of any international obligations. At present, China is communicating with Colombia on this matter,” Hua said.
