"What I had on my mind all the time was that diplomacy is to fulfill Japan's responsibility on the international stage and to bring benefits to the Japanese people. Our economy, agriculture, fisheries, security, medicine, infectious diseases and what not, international challenges are directly connected to domestic challenges. There are various differences of views within Japan on various matters, but bearing those differences in mind there are various issues on which Japan needs to cooperate on the international stage where Japan can make contributions. I really felt that overseas issues are directly connected to domestic challenges, and I have stated my views on the international stage while listening to the views of others."
