Prime Minister Shinzo Abe has today called for a leaders' summit or a foreign ministers' meeting between his country and China as soon as possible.
Sino-Japanese ties, often fragile, have been seriously strained since September when a territorial row over tiny islands in the East China Sea flared. Concerns that the conservative Japanese leader wants to recast Japan's wartime history with a less apologetic tone have added to the tensions.
"I think there should be a summit meeting and also a foreign ministers meeting as soon as possible ... I think such meetings should be held without pre-conditions," Abe said in response to a question at an academic conference in Singapore, the second stop on a trip that includes Malaysia and the Philippines.
China's Foreign Ministry said its door was always open for talks, but that the problem lay in Japan's attitude.
"The crux of the matter at present is Japan's unwillingness to face up to the serious problems which exist in Sino-Japan relations and it is avoiding having earnest talks and consultations with China," the ministry said in a faxed statement to Reuters.
Japan, it said, should "stop using empty slogans about so-called dialogue to gloss over disagreements".
Earlier on Friday, the defence ministry in Tokyo issued a policy report repeating Japanese concerns about China's military build-up and its activities near the islands.
China's Foreign Ministry said it hoped Japan would respect the concerns of neighbouring countries and "take the path of peaceful development and not artificially create and exaggerate tensions".
In his remarks, Abe also said that ties between Asia's two biggest economies were vital. Both, he said, benefitted from strong economic ties.
Abe made his comments two days after Japan scrambled fighter jets in response to a Chinese military aircraft flying for the first time through international airspace near its southern islands out over the Pacific.
Abe returned to office last December and cemented his grip on power in election to parliament's upper house last weekend. Attention has been focused on how he would now deal with thorny problems such as frayed ties with China and South Korea and how he would flesh out plans to revive Japan's stagnant economy.
BEING "AT EASE"
The Japanese leader has taken a tough line in the territorial dispute and on Friday repeated in a speech - without singling out Beijing - that it was not "coercive force" that would guide Asia.
But in his address to the conference, he added: "I am looking forward to the day when I can have amicable discussions with the leaders of China, an important neighbouring country for Japan in ... (a) spirit of being at ease with each other."
Tensions rose last year after Japan nationalised the islands, known in Japan as the Senkaku and as the Diaoyu in China.
Chinese and Japanese ships and aircraft have been playing a cat-and-mouse game near the isles, raising worries about an accidental clash that could escalate.
The United States has affirmed that the islands are included in its commitment under a U.S.-Japan security treaty.
But after Abe met U.S. Vice-President Joe Biden, who was also visiting Singapore, it restated its wish for tensions to subside.
"On regional security affairs, the vice-president reaffirmed the U.S. position on the East China Sea, including our alliance commitments, and highlighted the U.S. view that all sides should take steps to reduce tensions," the White House said in a statement after the meeting.
On Friday, four ships from China's newly formed civilian coast guard entered what Japan considers its territorial waters near the islands but left the area later without incident.
Abe served a brief and troubled term as premier from 2006-2007, during which one of his major accomplishments was to improve badly frayed ties with China.
