Japan toward People's Republic of China
-30Japan has provided China with official development assistance since 1979 and participated in bilateral agreements and dialogue, including the 2008 joint statement on advancing relations. Japanese government security cooperation with the United States and its positions on the Senkaku/Diaoyu Islands and Taiwan have been sources of friction with Beijing.
Overall relationship

The 1978 Treaty of Peace and Friendship and later cooperation frameworks support engagement, but they have not removed strategic rivalry or recurring political tensions.
