Chinese Foreign Minister Wang Yi told his Japanese counterpart at a meeting in Tokyo: "With both of us standing on a new starting point, I hope we will promote the further development of both nations by opening a new future of bilateral cooperation."
Relations between the pair are entering an "important phase of improvement and growth," Wang added, on a rare visit by a top Chinese official to Japan.
Tokyo is battling to stay relevant amid a string of summits on North Korea's nuclear programme in which Beijing is likely to be a major player.
With this in mind, Japan is pushing to host a trilateral meeting between Prime Minister Shinzo Abe, Chinese Premier Li Keqiang and South Korean President Moon Jae-in.
Bilateral visits by Abe and Chinese President Xi Jinping are also being planned.
China demonstrated its significant influence over its reclusive ally when Xi hosted the North's leader Kim Jong-un and his wife in Beijing last month.
With Moon and Trump also preparing to meet Kim, reported efforts by Japan to reach out to Pyongyang have gone ignored.
Meanwhile, Japan and China are also targets of Trump's steel and aluminium tariffs, with Beijing also targeted with a further heavy levy.
Japan's Foreign Minister Taro Kono and Wang did not specifically mention the proposed US trade policies, as its implementation and consequences were still unclear.
But they noted the global economy has dramatically changed during the eight years the bilateral dialogue has stalled.
"We must have fresh perspectives and think about ways of cooperation and coordination," said Kono.
