Secretaries-general of Japan's ruling coalition parties plan to undertake a three-day visit to Beijing next Monday, aiming to promote confidence-building between Japan and China.

Sadakazu Tanigaki of the Liberal Democratic Party and Yoshihisa Inoue of Komeito are expected to meet with Wang Jiarui, head of the International Department of the CPC Central Committee, during their visit to Beijing, according to Kyodo News.

The two sides are expected to agree on the resumption of "party-to-party exchange mechanism" that has been suspended since 2009.

The Secretaries-general will also try to explain Abe's push for legislation to allow Japan to exercise the right of collective self-defense.

Abe's planned statement for the 70th anniversary of the end of World War II, to be issued this summer, may also be taken up during the meetings.

Japan's Prime Minister Shinzo Abe expressed Japan's "deep remorse" over wartime invasion, and stressed Japan's aspiration to become a permanant member of the UN Security Council when delivering a speech on Monday at the United Nations University in Tokyo.

Japan feels more anxious and fretful on the historical issue, as countries prepare to commemorate the 70th anniversary of the victory against fascist forces in World War II, China Foreign Affairs University professor Zhou Yongsheng told Global Times newspaper on Monday.

The spotlight will be on former fascist powers, especially Japan, and their attitude toward their war crimes. Japan feels isolated and does not fit in well with these countries. Japan still taken an offensive approach and there's no deep introspection, Zhou added.
