President Bush has begun meetings with world leaders as part of the Asia-Pacific Economic Cooperation summit in Santiago, Chile.
The president is scheduled to hold one-on-one meetings Saturday, with Chinese President Hu Jintao, as well as leaders from Japan, South Korea, Indonesia, Canada, and Russia.
Mr. Bush is expected to use the meetings to encourage continued pressure on North Korea to end its nuclear weapons program.
In his weekly radio address later Saturday, Mr. Bush is expected to say that he hopes the day's meetings will strengthen ties across the Pacific and improve shared security.
On Sunday, the president is scheduled to meet with Mexican President Vicente Fox and to hold a news conference with Chilean President Ricardo Lagos.
The two-day APEC summit will also focus on global trade and terrorism.
