TOKYO, Feb. 7 (Xinhua) -- Leader of Japan's small ruling New Komeito Party Natsuo Yamaguchi said Thursday that he hopes Japan and China could hold a high-level summit in August to mend bilateral ties which scratched by territorial dispute, local media reported.
Speaking at a press conference at the Foreign Correspondents' Club of Japan, Yamaguchi said he hopes the date would preferably be on Aug. 12 that marks the 35th anniversary of the signing of Sino-Japan Treaty of Peace and Friendship, said Japan's Kyodo News Agency.
He, referring to the radar incident between the two countries vessels, said both countries should act with calm response and stressed the importance of dialogue so as to prevent contingencies.
He added that individual incident should not affect the overall bilateral relations.
Yamaguchi, who met with the Chinese Communist Party's leader Xi Jinping during his visit to China on Jan. 25, said Xi told him that he will seriously consider Yamaguchi's proposal of a bilateral summit.
Tensions have soared between China and Japan since last September after Japan unilaterally "nationalized" China's Diaoyu Islands, despite China's strong opposition.
