The French military is set to join international efforts to monitor ship-to-ship transfers of goods involving North Korea.
The move, which is a first for France, was disclosed by Japan's Defense Minister Takeshi Iwaya on Friday.
Receiving goods through the alleged method violates UN Security Council sanctions resolutions on North Korea.
Iwaya said a frigate and patrol aircraft from the French navy will join the monitoring efforts in the middle of this month at the earliest.
This comes after an agreement at the "two-plus-two" meeting of Japanese and French foreign and defense ministers in January.
Currently, Japan, the United States, Australia, Canada, the UK and others are involved in efforts aimed at maintaining sanctions against North Korea as part of pressure toward the country's denuclearization.
Iwaya said he welcomes France's participation. He said the international community is united in efforts to ensure the effectiveness of the UN Security Council resolutions. He added that Japan will continue closely cooperating with the other countries involved.
