Wang noted that exchanges between political parties are an important part of China-Japan relations.

"We hope that the two sides will deepen exchanges and cooperation, strengthen understanding and trust, consolidate the political foundation of bilateral relations, and create conditions for the steady and sustainable development of their relations," Wang said.

Yamaguchi said the Komeito Party is always committed to the friendship between Japan and China.

"We hope the two countries will join hands to shoulder responsibilities and make contributions to regional and world peace and prosperity," he said.
