The leaders of South Korea, the United States and Japan plan to hold a meeting in Washington in the coming weeks to discuss ways to increase pressure on North Korea, a news report said Thursday.

The three countries began to work out the details for a trilateral summit during the Nuclear Security Summit, Japan's Jiji Press reported, citing an unidentified Japanese official.

U.S. President Barack Obama is set to host a fourth and final Nuclear Security Summit from March 31 to April 1 in Washington.

The planned summit comes as the U.N. Security Council is working on a resolution for sanctions to punish North Korea for its recent nuclear and long-range missile tests.

Obama launched the biennial gathering of world leaders with a vision to make the world safer without nuclear weapons.

The U.S. hosted the inaugural meeting in 2010 and the following two summits were hosted by South Korea in 2012 and the Netherlands in 2014.

In 2014, President Park Geun-hye met with Obama and Japanese Prime Minister Shinzo Abe on the sidelines of the Nuclear Security Summit. (Yonhap)
