US President George W Bush has expressed the need for growth of democratic system across Asia.

In a lecture previous to the Asia-Pacific summit in Sydney, he stated free countries should work collectively in order to back up democratic bodies.

Mr. Bush singled out Burma, calling on the military administration to release all political prisoners, comprising opposition head Aung San Suu Kyi.

He also advised China to make use of next year’s Olympics to express ‘better receptivity.’

In his all-embracing lecture to business heads in Sydney, Mr. Bush told Australia and the United States were connected by common interests.

He added, “We seek an Asia-Pacific region that is growing in freedom and prosperity and peace.”

While lecturing on the eve of the 21-nation Asia-Pacific Economic Co-operation (Apec), Mr. Bush invited associates to help break the stalemate in the Doha round of trade discussions.

Mr. Bush sounded out the round was a "once-in-a-generation" opportunity and that America was ready to show flexibility.

“The United States is committed to seizing this opportunity and we need partners in this region to help lead the effort,” He narrated the business heads at Sydney’s Opera House.

He also demanded for teamwork on climate change and stated India and China had to be part of the action.

The US leader described the talks as friendly regardless of the reality they undertook spiky issues for example religious freedom and exchange rates.

Security is very tight in the city, with huge demonstrations projected at the weekend. On Thursday Mr. Bush held discussion with his Chinese counterpart Hu Jintao.

A 5km (three-mile) barrier has been erected across the city’s central business district and more than 5,000 police and troops are patrolling the streets.
