Cuba announced on Tuesday that weapons found on a North Korean ship close to the Panama Canal were “obsolete” Soviet-era arms, which the communist island had sent to Pyongyang for repair.
The declaration came a day after Panama said it had found military equipment, which it believed to be missiles, after impounding the ship and conducting a drugs search.
Panama earlier on Tuesday urged UN inspectors to scrutinize the cargo, which could constitute a violation of the strict arms sanctions imposed on North Korea over its nuclear program.
However, Cuba, one of North Korea’s few allies, claimed the shipment as its own, with the Cuban foreign ministry listing 240 tonnes of “obsolete defensive weapons,” including two anti-aircraft missile systems as being on board.
There were also “nine missiles in parts and spares,” various Mig-21 aircraft parts and 15 plane motors, “all of it manufactured in the mid-20th century” and “to be repaired and returned to Cuba,” it said.
“The agreements subscribed by Cuba in this field are supported by the need to maintain our defensive capacity in order to preserve national sovereignty,” the ministry said in an English-language statement.
Panamanian President Ricardo Martinelli tweeted a photograph of the haul, which experts earlier on Tuesday identified as an aging Soviet-built radar control system for surface-to-air missiles.
Martinelli’s government said the munitions were hidden in a shipment of 100,000kg of bagged sugar aboard the North Korean-flagged Chong Chon Gang.
Panamanian Minister of Security Jose Raul Mulino told RPC radio that the affair now is a matter for UN investigators.
The US hailed the discovery.
“We stand ready to cooperate with Panama should they request our assistance,” US State Department spokesman Patrick Ventrell said, reiterating that any shipments or “arms or related material” would violate several UN Security Council resolutions.
The magazine Jane’s Defence Weekly said on Tuesday that the photograph tweeted by Martinelli appeared to show an “RSN-75 ‘Fan Song’ fire-control radar system.”
The weapons were developed in 1957 and frequently used during the Vietnam War.
Panamanian officials said on Monday that the crew resisted the search on Friday, and that the ship’s captain attempted to commit suicide after the vessel was stopped. It was sailing from Cuba toward the canal with a crew of about three dozen and was stopped by drug enforcement officials and taken into port in Manzanillo.
A Panama government spokesman said an examination of the ship by weapons specialists may take as long as a week.
The vessel was being held in a restricted zone, and the crew had been detained, officials said. So far, no drugs have been found on board.
North Korean Army Chief Of Staff General Kim Kyok-sik visited Cuba last month and said the two countries were “in the same trench.”
North Korea carried out a third nuclear weapons test in February, triggering tighter UN sanctions.
Experts say it is unclear whether the North has the technology to build a nuclear warhead for a missile.
UN sanctions bar the transport of all weapons to and from North Korea apart from the import of small arms. Several of the country’s ships have been searched in recent years.
Pyongyang has yet to comment on the latest incident.
Five percent of the world’s commerce travels through the century-old Panama Canal, and that is expected to increase following the completion of a major expansion project.
