The Thai Prime Minister, Abhisit Vejjajiva, is prepared to include discussion of his Australian counterpart’s push for a new regional body at the East Asia Summit.
Thailand is hosting the Asian meeting.
The Thai leader and Australian counterpart Kevin Rudd have had talks in London ahead of the G20 summit.
Mr Rudd has been raising his idea of an Asia Pacific Community during his overseas trip.
He has talked about it with the US Secretary of State, Hiliary Clinton, and senior US senator John McCain.

A spokesman for Mr Rudd says the Thai leader told the Australian during their talks he would welcome a discussion of the new community proposal at the Asian summit.
Mr Rudd has also met Indonesian President Susilo Bambang Yudhoyono and Russian President Dmitry Medvedev in London.
He and the Indonesian leader discussed the need for help for developing nations.
The president expressed support for Australia’s decision to provide Indonesia with a standby loan should it be necessary.
While the G20 is not likely to discuss detail of future fiscal stimulus, the Indonesian and Australian leaders agreed on the need for coordinated stimulus.
Like other leaders, Mr Rudd has engaged in an intensive round of diplomacy during the opportunity presented by the actual four-hour G20 summit meeting on Thursday.
