Tokyo, Japan (Reuters): Japanese Trade Minister Hiroshige Seko said on Friday that the Japanese government has decided to broaden unilateral sanctions against North Korea by two years.

Tokyo will continue its prohibition of all trade between Japan and North Korea and ban on all North Korean ships from entering Japanese ports, Kyodo News reported earlier.

Earlier on Wednesday, North Korea conducted a ballistic missile test off its east coast, South Korea's military said, the latest it has test-fired in recent months.
