刘云山
On 5 June 2013, Nonaka led a delegation including former Prime Minister Yukio Hatoyama to visit Beijing and confer with Liu Yunshan, a member of the Politburo Standing Committee of the Communist Party of China. Nonaka told reporters that as a young politician in the 1970s, he had heard Kakuei Tanaka state that an agreement had been reached to shelve the dispute between Japan and China over the Senkaku Islands in order to normalize relations between the countries. Chief Cabinet Secretary Yoshihide Suga denied the claim as "baseless" and alleged that Nonaka had been influenced by "Chinese hospitality."
