SEOUL, March 27 (Yonhap) -- Nuclear-related materials confiscated in Japan from a ship carrying cargo from North Korea were not bound for Myanmar, the chief political advisor to President Thein Sein said Wednesday, denying media allegations of nuclear cooperation between the North and Myanmar.

The Japanese government said last week that it had seized aluminium alloy rods that could be used to make nuclear centrifuges from a Singapore-flagged ship, which was carrying cargo from North Korea. Media reports said the ship was bound for Myanmar.
