President Bush is meeting with the European Union for the last time in Slovenia this week.
One of the President's priorities at the summit is how to handle Iran's nuclear program. He wants Britain, Germany and France to join the U.S. and threaten Iran with financial sanctions.
"They can either face isolation, or they can have better relations with all of us," Bush said Tuesday. "Now's the time for all of us to work together to stop them."
He said Iran "can't be trusted with enrichment."
The global economy is also a big issue at the summit.
Bush says he wants the dollar to grow stronger, but he said the world economies will end up setting the value of the dollar.
A weak dollar helps U.S. businesses sell their products internationally, because they're cheaper. However, that hurts businesses in other countries and European allies have been urging the President to be more aggressive in defending the dollar.
On the subject of global warming, Bush said, "I think we can actually get an agreement on global climate change during my presidency," which ends on Jan. 20, 2009.
But he said that any global warming agreement reached would be ineffective without China and India
European members and the United States may have dissimilar approaches to some of its common challenges Slovenian Prime Minister Janez Jansa, the president of the European Council, said.
"Make no mistake about it, there will be differences about how to approach different issues," Bush said. "And that's OK."
