WASHINGTON - SOME of the most experienced Asian and US foreign policy experts want the new US president to give urgent attention to Asia amid waning US influence and a shifting power balance in the region.

The Asian experts warned in candid reports compiled by the US-based Asia Foundation that although the United States has been the regional power in Asia since the end of World War II, there was now uncertainty about the relevance of its power given current regional dynamics.

'The United States may still hold the balance of power in Asia, but does this mean that the US necessarily holds the most influence?' they asked in one report.

They compiled the report after chairing workshops in the region that sought feedback on US policies in Asia.

The American experts, on the other hand, wanted the successor of current President George W. Bush to pay 'urgent attention' to Asia.

'Size matters and they have it', said former US Under Secretary of State Michael Armacost and ex-Assistant Secretary of State J. Stapleton Roy.

Asia is home to more than half the world's population and six of the ten largest countries, produces more than 30 per cent of global exports and controls a much larger share of the world's savings pool, they said.

While the United States has been preoccupied with the situation in the Middle East, 'the Asian balance has been shifting quietly, if inexorably, in the direction of others', they said.

'China, Japan, India, and Russia are casting a longer shadow'. In addition, they said, it was in Asia that the interests of the great powers intersect most directly, and the most consequential emerging powers - China and India - are located.

'We must devote to Asian issues the attention and resources their intrinsic importance to the United States demands'.

US policy to Asia has scarcely been mentioned by Democratic candidate Barack Obama and his Republican rival John McCain during the US presidential election campaign, and the region east of Afghanistan has not been on their travel itineraries.

'We strongly recommend that you put Asia onto the agendas for the upcoming political conventions', Asia Foundation President Douglas Bereuter said in a statement sent this week to Republican and Democratic foreign policy campaign advisors accompanying reports by the Asian and American experts.

'Good foreign policy to Asia is critical for the next administration - and should be addressed by the platforms during the conventions' of the two parties ahead of the November elections, Mr Bereuter said.

The Asian experts also wanted the new US administration to 'actively support a regional architecture' in rapidly growing Asia, including signing a non-aggression accord of the Association of Southeast Asian Nations (Asean).

'There is a growing sense of Asian regionalism; if the US continues to take a narrow perspective on this issue, it stands to lose influence in the region', they warned.

Also sought were steps to improve US trade with the region, including providing fast-track trade negotiating authority powers to the new president, to hold a dialogue on energy security and climate change with Asia, and to undertake public diplomacy efforts with the Asian people.

The American experts wanted a new US strategy to counter-terrorism in the Middle East and South Asia that neither overshadows nor underrates a host of other foreign policy challenges.

They also called on the United States to promote respect for democracy and human rights by providing an example for others to emulate - by keeping American doors open to Asians who seek access to US colleges and universities and by strengthening military education and training programmes.
