Asserting the global financial crisis is "not a failure of the free market," President George W. Bush on Thursday called on the world leaders meeting this weekend to agree on a modest set of reforms aimed at preventing future collapses.

Bush's main message to the leaders about to converge on Washington: Reforms won't help if abandon the free market and restrict trade.

"Government intervention is not a cure-all," Bush said in a speech to the Manhattan Institute.

The president delivered a vigorous defense of free-market capitalism and easier global trade to frame his approach to the high-level gathering he's hosting in Washington this weekend. Bush invited representatives of some of the world's biggest industrial democracies, emerging nations and international bodies to Washington to start developing a more coordinated world response to the economic woes that have millions of people struggling to keep their jobs, their homes and their hopes.

With the severe economic downturn threatening to end Bush's tenure on a sour note before President-elect Barack Obama takes over, he will host the leaders at a White House dinner Friday and review causes and solutions for the financial mess Saturday.

It was fitting that Bush's argument against regulatory overreach was being delivered not in Washington but from the heart of Wall Street. His speech venue was the venerable Federal Hall that was home to the first Congress and is within shouting distance of New York Stock Exchange.

Bush called for reforming the global economy to strengthen it long-term and said leaders at this weekend's meeting would "discuss specific actions we can take."

Among the possible agreements, Bush listed:

— bolstering accounting rules for stocks, bonds and other investments so investors have a clearer sense of the true value of what they buy.

— requiring "credit default swaps" — a type of corporate debt insurance — to be processed through a central clearinghouse. That would help provide crucial information on the parties involved in these complex, unregulated products. Prices for this insurance soared in the aftermath of the Lehman Brothers' bankruptcy and imperiled American International Group, a major insurer of this kind of corporate debt.

— taking a fresh look at rules aimed at preventing fraud and manipulation in trading of stocks and other securities.

— better coordinating financial regulations among countries.

— Giving a wider variety of countries voting power at the International Monetary Fund and the World Bank.

Notably absent from his speech was any talk about what the U.S. might do to bail out the troubled auto industry or the debate over a second U.S. stimulus package.

"The crisis was not a failure of the free market system," Bush said. "And the answer is not to try to reinvent that system."

Bush's case against excessive government intervention comes as some critics think his administration already is doing just that. The federal dollars being spent or put on the line to rebuild the nation's financial system could easily run into the trillions. Already the Bush administration has enacted a $700 financial rescue package, backed the purchase of investment bank Bear Stearns, bought stock in leading banks, engineered a government takeover of mortgage giants Fannie Mae and Freddie Mac, guaranteed money market fund holdings and funneled billions to stabilize troubled insurance giant American International Group.

At the same time, the president aggressively defended the U.S. against charges from around the world that it was insufficient regulation in his country that led to the credit collapse worldwide. This was his way of pushing back against both the criticism and the calls by allies for more intrusive rules. Heading into the meeting, Europeans are seen as looking more urgently for broad changes and tighter universal banking regulations than is the United States.

"Many European countries had much more extensive regulations and still experienced problems almost identical to our own," Bush said.

Some critics have said that lax oversight by regulators in the U.S. and elsewhere failed to detect problems and respond with action that could have prevented the meltdown. The crisis began with the collapse of the U.S. housing market, which froze credit, then the broader financial sector and finally rippled overseas.

"History has shown that the greater threat to economic prosperity is not too little government involvement in the market but too much," Bush said. "It would a terrible mistake to allow a few months of crisis to undermine 60 years of success."

Dan Price, Bush's deputy national security adviser for international economic affairs, rejected suggestions of discord with other nations and said it was "grossly inaccurate" to suggest the U.S. was not taking a firm lead in reform.

"We are no less committed to fixing the problems, and addressing regulatory and other deficiencies, than any other leader," he said.

While in New York, the president addressed a United Nations conference on religious tolerance and met privately with King Abdullah of Saudi Arabia.

The summit is just the first in a series intended to deal with the enormity of the economic meltdown, and the next meeting won't be until after Bush leaves office on Jan. 20.

In the United States alone, the nation's jobless ranks zoomed past 10 million last month, the most in a quarter-century, as 240,000 more people lost jobs. In the latest dire sign, American automakers say they are struggling to survive.

Obama is steering clear of the summit but will have a couple representatives available to meet with leaders on his behalf.

Besides the United States, the countries represented will be Argentina, Australia, Brazil, Britain, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea and Turkey. Those countries and the European Union make up the so-called G-20.
