Within the ruling Liberal Democratic Party, to break the existing deadlock, Kenzo Matsumura of the Japanese House of Representatives and others formed a foreign policy group in 1959. This group spoke highly of China’s importance to Japan’s devel- opment on the grounds of national interests rather than ideology and national sentiments, played a bridg- ing role in the political communication between China and Japan, and created a precedent for the nontraditional improvement of international relations in Japan.
