South Korea's new president Park Geun-Hye and Japanese Prime Minister Shinzo Abe held telephone talks Wednesday and agreed to co-operate on their reaction to North Korea's latest nuclear test last month.
In their brief conversation, the first since Park took office last month, the two leaders agreed to continue working with Washington to push for a UN resolution on Pyongyang, according to major Japanese media, including Jiji Press and the Nikkei.
Park stressed the importance of the history between the two nations, indirectly reminding Abe about long-held South Korean animosity over Japan's brutal 1910-45 colonisation of the Korean peninsula, the reports said.
Abe meanwhile called on South Korea's first female leader to jointly build "future-oriented" relations while taking account of history, they said.
Abe also invited Park to visit Japan, the Nikkei said.
At the United Nations on Tuesday, the United States and China called on the Security Council to sanction North Korean diplomats and "illicit" cash transfers to step up pressure on Pyongyang over its nuclear programme.
Diplomats said a vote on the sanctions resolution could be held on Thursday.
