Japan says it is engaged in talks with China to resolve a territorial dispute that has disrupted ties between the two Asian powers, the Voice of America reports. Chief Cabinet Secretary Osamu Fujimura on Wednesday confirmed reports that Vice Foreign Minister Chikao Kawai secretly met last week with senior Chinese officials in Shanghai. He said the talks were part of Tokyo’s effort to continue to communicate with Beijing “at various levels” regarding the island dispute in the East China Sea.Meanwhile, senior Chinese officials have apparently rejected efforts by a U.S. diplomatic delegation to mediate the dispute. China’s official Xinhua news agency says Vice Premier Li Keqiang stressed China’s “solemn stance” on the issue during Tuesday meetings with former White House National Security Advisor Stephen Hadley, ex-deputy Secretary of State Richard Armitage, and others. Armitage and Hadley met with Japanese Prime Minister Yoshihiko Noda on Monday in Tokyo, where they reportedly discussed the island dispute and worsening China-Japan relations.
