NEW YORK (Kyodo) Japan has given up plans to submit a new draft resolution on U.N. Security Council reform this spring, U.N diplomatic sources said Tuesday.

It is the first formal notification of Tokyo's internal decision to other members of the so-called Group of Four -- Brazil, Germany and India -- that were jointly working to become the new permanent UNSC members, the sources said.

"(The Japanese side said) they are going to drop (the plan)" at a meeting Monday at Japan's permanent mission to the United Nations, said one of the sources, who asked not be named due to the sensitivity of the issue.
