Planners of next year’s Asia-Pacific Economic Cooperation summit — due to be held in Honolulu in November — are being given an opportunity to think about security this week.

The safety of large international events like APEC is the theme of the state’s annual Asia-Pacific Homeland Security summit, scheduled to be held this year in Waikiki tomorrow and Tuesday.

Maj. Gen. Randall Marchi of the Pennsylvania Army National Guard, who served as the joint task force commander for the G-20 Summit held in Pittsburgh in September 2009, is due to speak.

He’ll be joined by Bud Mercer, the integrated security chief operating officer for the Vancouver Olympics. Khoo Boon Hui, who is both the president of Interpol and a senior home affairs ministry official in Singapore, the host of 2009 APEC summit, is also expected to talk.

Several panelists, including Gregg Yamanaka, the CEO of the APEC 2011 Hawaii host committee, are scheduled to share what they saw at this year’s APEC meeting in Yokohama, Japan.

Though the discussion will likely focus heavily on APEC, officials planning for other prominent public events — like annual ceremonies marking the 1941 attack on Pearl Harbor — are also expected to attend and benefit from the discussions.

“APEC is obviously the big guy. But there are other small ones that (have) very high visibility,” said Lorinda Wong-Lau, the conference coordinator. “Everybody who has to plan for these kind of things — this is who our audience is. The people speaking are all senior people who have gone through this in their different locations.”

About 450 federal, state and county officials are expected to attend the conference at the Sheraton Waikiki.

APEC’s 21 members take turns hosting their annual meetings. President Barack Obama decided last year he would host the heads of state conference in his hometown of Honolulu.
