"Since previous year, Japan has, in relations with China, displayed a positive message and friendly attitude", Wang said at the meeting, adding that he hoped that the visit would help the two countries move towards better ties. Japan has come in for criticism from US President Donald Trump on trade and been hit with tariffs on steel and aluminium, but Japan has not yet threatened counter-tariffs.
Japanese Foreign Minister Taro Kono and his Chinese counterpart, Wang Yi, are chairing the event.
Li is set to visit Japan next month for a trilateral summit with Abe and South Korean President Moon Jae In. The U.S-North Korea talks are aimed at ending a stand-off over Pyongyang's development of nuclear weapons and ballistic missiles.
Noting that this year marks 40 years since the signing of a bilateral peace and friendship treaty, Kono said he and Wang agreed to work for the improvement of bilateral relations across the board.
"I would like to regard (Mr Wang's visit) as a major step forward in our efforts towards improving Japan-China relations", Mr Kono said at the start of their meeting. Kono said he and Wang agreed that their countries need to further develop bilateral relations in order to stabilize the waters. The dispute over islands in the East China Sea - known as the "Senkakus" in Japanese and the "Diaoyu" by the Chinese - remains a source of tension.
Financial markets have been roiled recently over fears that a full-blown US-China trade war could shatter global trade and economic growth, and these issues are likely to be high on the agenda, along with Japanese cooperation on projects in China's "Belt and Road Initiative".
Kono met Wang in Beijing in January.
China and Japan have resumed high-level economic talks after a hiatus of almost eight years in a sign of improving ties in their often-frosty relationship.
Japan's Foreign Minister Taro Kono and Wang did not specifically mention the proposed United States trade policies, as its implementation and consequences were still unclear.
Japanese Economy, Trade and Industry Minister Hiroshige Seko and Chinese Commerce Minister Zhong Shan held separate talks in Tokyo on Sunday, discussing the future of economic ties.
