TOKYO (AP) — Showing solidarity with Japan, President Barack Obama affirmed Thursday that the US would be obligated to defend Tokyo in a confrontation with Beijing over a set of disputed islands, but urged all sides to resolve the long-running dispute peacefully.
Wading cautiously into a diplomatic minefield, Obama insisted the US takes no position on whether the islands in the East China Sea are ultimately in the dominion of China or Japan. But he noted that historically Japan has administered the islands, triggering America’s treaty obligations to defend its ally should tensions escalate militarily.
‘‘We do not believe that they should be subject to change unilaterally,’’ Obama said at a news conference with Japan’s Prime Minister Shinzo Abe. ‘‘What is a consistent part of the alliance is that the treaty covers all territories administered by Japan.’’
The dispute over the islands, called Senkaku by Japan and Diaoyu by China, has badly strained relations between the two Asian powers. Although Obama has sought to avoid getting dragged in to territorial disputes an ocean away, Japan and other US allies see the disputes through the broader lens of China’s growing influence in Asia, where Obama arrived Wednesday at the start of a four-nation, eight-day tour.
China is not on Obama’s itinerary, but concerns about the Asian powerhouse are trailing the president nonetheless. Beijing is watching closely for signs that US is seeking to limit China’s rise, while smaller nations are looking to Obama for affirmations that his vaunted push to increase US influence in Asia hasn’t petered out.
Obama’s advisers insist that the trip — and the White House’s broader Asia policy — is not designed to counter China’s growing power, and they say the president is not asking Asian nations to choose between allegiance to Washington or Beijing.
‘‘We want to continue to encourage the peaceful rise of China,’’ Obama said.
Seeking to inject fresh urgency into trade talks, Obama said the time is now to resolve issues hindering completion of the Trans-Pacific Partnership. The US has been leading the 12-nation negotiations, but an end-of-2013 deadline was missed and there are few signs of progress toward resolving conflicts with Japan over tariffs and access to Japan’s auto market.
At the same time, as Obama pressed his case in Tokyo, he was unable to convey the full backing of Congress, which would have to ratify any such pact. Lawmakers, including many of Obama’s Democratic allies, have thus far refused to give Obama the fast-track authority needed to ensure an up-or-down vote on the final agreement.
‘‘Abe’s got to deal with his politics, I’ve got to deal with mine,’’ Obama said.
On the island dispute, Obama encouraged the parties to work through the issue ‘‘through dialogue’’ and urged both sides to ‘‘keep the rhetoric low.’’ He downplayed the US commitment to defend Japan as a matter of historical fact rather than a rebuke to China.
‘‘The treaty between the US and Japan preceded my birth, so obviously this isn’t the red line that I’m drawing,’’ the president said.
China has said it firmly opposes the application of the US-Japan treaty to the dispute over the islands, which sit in strategically important waters to China’s east. China’s government said this week that ‘‘the so-called Japan-US alliance’’ should not harm China’s territorial rights, urging the US to play a constructive role in promoting regional stability.
Abe said he and Obama agreed to cooperate on engagement with China and other issues, including Okinawa, where the US military presence remains a source of tensions. ‘‘The Japan-US alliance is more robust than ever before,’’ Abe said through a translator.
Addressing another source of tension in the region, Obama said he’s not optimistic North Korea will change its behavior in the near future. But he said he’s confident that by working with Japan, South Korea and others — especially China — the US can apply more pressure so that ‘‘at some juncture they end up taking a different course.’’
Underscoring his concerns about Pyongyang’s behavior, Obama met Thursday with relatives of Japanese citizens that the White House said were abducted by North Korea. Obama recommitted to working with Japan to address the North’s ‘‘deplorable treatment of its own people,’’ the White House said.
Later Thursday, Obama planned to return to the Imperial Palace for a state dinner. He also planned to visit the Meiji Shrine, which honors the emperor whose reign saw Japan emerge from over two centuries of isolation to become a world power.
Obama’s Asia swing is aimed at reaffirming his commitment to the region even as the crisis in Ukraine demands US attention and resources elsewhere. The ominous standoff between Ukraine and Russia threated to overshadow the trip as the president weighs whether to levy new economic sanctions on Moscow.
The president’s stops in Japan, South Korea, Malaysia and the Philippines serve as something of a do-over after he canceled a visit to Asia last fall because of the US government shutdown. The cancellation provided fresh fodder for those in the region who worry that the White House’s much-hyped pivot to Asia is continually taking a backseat to other foreign and domestic priorities.
Obama began his day with a call on Emperor Akihito at the Imperial Palace, a lush, park-like complex surrounded by modern skyscrapers where he was greeted by a military honor guard and children holding US and Japanese flags. After taking in the scene, the president, emperor and empress walked along a maze of red carpet into the palace for a private meeting, with US Ambassador Caroline Kennedy and other aides trailing behind.
When Obama pointed out that the last time he met the emperor, he didn’t yet have any gray hairs, the emperor offered the president a gracious excuse: ‘‘You have a very hard job.’’
