Burmese authorities say they have inspected a North Korean cargo ship after allowing it to dock at a Burmese port on Saturday.
A Burmese government statement says authorities did not find any suspicious material or military equipment on board the vessel.
Burma says it permitted the North Korean ship to dock on humanitarian grounds, and supplied the crew with water. The vessel left Burma on Monday, but the government did not say where it was going.
Japanese media have reported that U.S. authorities have been tracking the ship since it left North Korea last month, suspecting the vessel may be carrying military hardware.
A U.N. Security Council resolution adopted last month calls on member states to inspect cargo ships traveling to and from North Korea to prevent the trade of weapons technology.
