Japan's Cabinet plans to approve Friday new unilateral sanctions against North Korea that would for the first time freeze assets of entities and individuals not associated with nuclear and missile development, a government official said.

At their trilateral summit meeting in Germany earlier this month, the leaders of Japan, the United States and South Korea agreed to increase pressure on Pyongyang to push it to "refrain from provocative and threatening actions."

The United States has indicated it will impose additional sanctions on Chinese companies doing business with North Korea.

The new sanctions by the Japanese government will be levied on five organizations including two Chinese firms and nine individuals that are engaged in financial services, transport operations and exports of minerals such as coal, the official said.

North Korea's testing of nuclear and ballistic missile technology is banned by the United Nations and is the subject of multiple international sanctions.
