Singapore ? President Bush wrapped up a summit of Asian-Pacific leaders Tuesday and prepared for a brief, high-security visit today to the Indonesian island of Bali in a gesture of support for the nation’s efforts to combat terrorism.

More than 200 people were killed in Bali last October when Islamic militants bombed a pair of nightclubs, and Bush has described Southeast Asia as the “second front” in his “war on terrorism,” behind Iraq.

Bush is to meet with President Megawati Sukarnoputri, whom he has praised for cracking down on terrorist networks, particularly Jemaah Islamiah, which is blamed for the Bali blasts. Indonesia has convicted about 30 people in connection with the bombings and arrested about 100 alleged Jemaah Islamiah members.

But the president also intends to meet with Muslim leaders during his four-hour visit to try to combat a perception common in the Muslim world that his anti-terrorism effort is in effect a war on Islam.

Indonesia, home to 210 million people, is the world’s most populous Muslim nation.

Security was extremely tight for the visit, and Bush was not scheduled to leave the grounds of the airport. But an administration official said the president was confident that the Indonesians had taken all necessary precautions.

“I’m planning to get out alive, and I think the president is too,” the official said. “Security concerns are important, but the Indonesians are working hard with us.”

Bush’s trip to Bali comes after a stop in Singapore, where he dined with Prime Minister Goh Chok Tong after Tuesday’s conclusion in Bangkok, Thailand, of the annual summit of the 21-member Asia-Pacific Economic Cooperation forum. Leaders ended the meeting with a new commitment to combat terrorism and enhance security in the region.

“We agreed that transnational terrorism and the proliferation of weapons of mass destruction pose direct and profound challenges to APEC’s vision of free, open and prosperous economies,” the leaders said in a statement. “We agreed to dedicate APEC not only to advancing the prosperity of our economies, but also to the complementary mission of ensuring the security of our people.”

The United States won a pledge from APEC to devise ways to halt the spread of shoulder-fired anti-aircraft missiles, which threaten to disrupt commercial traffic.

In a measure of the U.S. concern, the White House decided that only planes equipped with anti-missile technology could make the flight into Bali. A plane chartered by the White House news corps was not permitted to make the trip; instead, officials allowed a small group of reporters to fly to Bali on a presidential support plane.

After his visit to Bali, Bush plans to fly to Australia, the final stop on his six-nation, seven-day regional tour.
