The Japanese government is planning a trilateral meeting with the United States and South Korea as early as next month to solidify a common stance on the North Korean nuclear standoff, Kyodo News agency reported Thursday. The meeting will most likely occur in Seoul, the South Korean capital, Kyodo said citing unidentified government officials. South Korea has differed with the United States and Japan over U.N. sanctions imposed against North Korea for its first-ever nuclear test this earlier this month, and the meeting is aimed at enhancing cooperation between the allies, the report said.
