"I hope that we will be able to discuss what Japan and China can work together on in the worldwide arena, not just bilateral issues", Kono told reporters on Friday.
Japan's Kyodo News and NHK reported that Chinese State Councilor and Foreign Minister Wang Yi visited Japan on Sunday and held talks with his Japanese counterpart Taro Kono to discuss ways to improve China-Japan ties and to enhance their cooperation on the North Korean nuclear issue.
They agreed that Japan would host a trilateral summit between Prime Minister Shinzo Abe, Chinese Premier Li Keqiang and South Korean President Moon Jae-in, without setting a date. The neighbours remain at odds, however, over China's growing military presence in the South China Sea, through which much of the region's sea-borne trade sails, and a dispute over ownership of uninhabited islets in the East China Sea, known as the Senkaku in Tokyo and the Diaoyu in Beijing.More news: Tax deadline: Things to know about filing taxes
But Tokyo is eager to get the relationship back on a firmer footing, especially as it fears being shut out of negotiations on North Korea's nuclear programme in which Beijing is likely to be a major player. He and Kono discussed a broad range of issues, including North Korea, Kono on Sunday night. Japan has come in for criticism from U.S. President Donald Trump on trade and been hit with tariffs on steel and aluminum, but Japan has not yet threatened counter-tariffs.
"We had direct and in-depth discussions on North Korea in light of the current situation", he told reporters after the meeting, without revealing details.
"We would like to co-operate further towards the common goal between Japan and China, of establishing a complete, irreversible and verifiable denuclearization of North Korea", Kono said as the two began talks in Tokyo.More news: Pro-Western Milo Djukanovic sweeps back into power in Montenegro
Wang said the visit was a response to Japan's positive attitude toward China.
The visit by Wang, a veteran Japan handler who had served as an ambassador to Tokyo, comes as the world's second and third largest economies attempt to ease tension, caused by longstanding disputes over maritime claims and Japan's wartime legacy.More news: Oladipo, Pacers Hand LeBron, Cavaliers Game 1 Playoff Defeat
