Japanese and Chinese leaders entered talks today with their Asian counterparts focused heavily on whether the region should pursue an EU-style bloc, and whether Washington should be involved.
Making a case for an East Asian Community at a summit of Asian leaders in Thailand, prime minister Yukio Hatoyama said there should be some US involvement in the bloc, which faces stiff obstacles including Japan's historic rivalry with China.
It was unclear how a US role would work. But the comment may help allay concern in some countries that such a body would ultimately fail by shutting out the world's biggest economy.
Mr Hatoyama may also be trying to defuse US-Japan tension over the long-planned reorganisation of the American military presence in Japan, the first big test of ties between Washington and the new Japanese government.
"Japan places the US-Japan alliance at the foundation of its diplomacy," Mr Hatoyama said at the meeting, according to a Japanese government spokesman.
"I would like to firmly promote regional cooperation in East Asia with a long-term vision of forming an East Asian Community." Several Southeast Asian leaders expressed support for the bloc, but none spoke of a US role at the meetings.
The talks are part of a three-day leaders' summit which got off to a rancorous start on Friday, marred by a diplomatic spat between Thailand and neighbour Cambodia, a trade feud over Filipino rice and a few no-shows in the 10-member Association of South-East Asian Nations (Asean).
China had a very different message at the meetings, signalling possible trouble ahead for Hatoyama. While he promoted a new community, Chinese Premier Wen Jiabao focused on the current one, delivering what Chinese state media described as a six-point proposal for strengthening links with Asean.
This included developing a recently signed China-Asean free trade pact and accelerating regional infrastructure construction.
An Asean statement summing up talks within its own members urged its most recalcitrant state, Myanmar, to ensure elections next year are free and fair, though it stopped short of seeking the release of detained pro-democracy icon Aung San Suu Kyi.
That came a day after Asean launched a human rights commission as part of a plan to build an economic and political community by 2015, and drew a scathing rebuke from rights activists who said it was toothless and lacked independence.
The region's leaders also called on North Korea to return to six-way nuclear disarmament talks.
The summit in the resort town of Hua Hin gave Asia's economic titans, China and Japan, a chance to jockey for influence in Southeast Asia, a region of 570 million people with a combined $1.1 trillion economy, as it pulls out of recession.
Japan's new government sees its influence bound to the East Asian Community, an idea inspired by the European Union that would account for nearly a quarter of global economic output.
It would encompass Japan, China, South Korea, India, Australia and New Zealand, along with ASEAN countries.
After meetings with China, Japan and South Korea, Asean holds talks on Sunday with India, Australia and New Zealand.
Australian prime minister Kevin Rudd on Sunday will push another idea for a new, separate forum of Asia-Pacific nations to respond to regional crises.
