The fifth Annual Forbes Global CEO Conference was officially opened in Sydney, Australia's biggest city, Tuesday, at which world business leaders will discuss the best ways to nurture and capitalize on innovation, as well as revealing the latest international business trends.

About 350 world's leading CEOs, presidents and senior level executives from Asia, Europe, South America, Australia and the United States will attend the conference at Sydney Opera House.

Themed "The Next Move," the conference will last until Thursday night,

Steve Forbes, president, CEO and editor-in-chief of Forbes, announced the opening of the conference jointly with Australian high-level officials.

"We have had an exceptional response to this year's conference and I look forward to discussing some important business issues with all of the delegates during the three day event," Forbes said.

Security was beefed up at the Sydney Opera House as dozens of police began patrolling barricades on the forecourt Tuesday morning, which was locked down Monday for the first time amid security fears for the business leaders attending the conference.

Thousands of activists from left-wing groups, the anti-war movement, anarchists and environmentalists, as well as school children, are expected to hold protests during the conference.

The Opera House, the city's landmark, will also be closed for tourists until the conference closes on Thursday night.
