The Chinese government says it's working to help assist the crew of a Chinese vessel currently being detained in Columbia.

The ship was seized over the weekend in the port of Cartagena with cargo destined for Cuba.

Columbian authorities allege the Chinese ship is carrying illegal supplies.

The Chinese government is denying the allegation.

Foreign ministry spokesperson Hua Chunying.

"As far as I know, the ship was carrying ordinary military supplies from China to Cuba, and no sensitive items were involved. Relevant cooperation does not violate Chinese laws and regulations, nor China's international obligations."

The ship was detained on Saturday by Colombian authorities after gunpowder and other military materials were found during an inspection.

The captain of the vessel is currently being detained.
