A Singapore court has fined a shipping company nearly $127,000 for wiring money used to transport fighter jets and surface-to-air missile systems from Cuba to North Korea in 2013 in violation of bans on helping Pyongyang build up its weapons programs.

The haul, hidden under heaps of sugar and discovered by Panamanian authorities, was the biggest load of arms and related materials ever to be intercepted on its way to or from the isolated North.

The court found that Singapore-registered Chinpo Shipping Company had transferred tens of thousands of dollars for the shipment without conducting due diligence.

District Judge Jasvender Kaur said Friday the fine had to be a deterrent due to strong public interest in preventing breaches of U.N. sanctions.
