Japan decided in a Cabinet meeting Friday to extend by one year its economic sanctions on North Korea.

Tokyo made the decision, citing the North’s refusal to return to the six-party denuclearization talks and its refusal to launch a new investigation into abducted Japanese citizens after agreeing in August 2008 to do so.

The sanctions ban North Korean ships from entering Japanese ports and prohibit the import of all goods from North Korea.

This is the sixth extension of Japan’s economic sanctions on North Korea since the Liberal Democratic Party put them in place in 2006 in retaliation for North Korea’s launching of missiles and nuclear tests.
