WASHINGTON  President Bush sought to present a united global front in responding to the financial crisis on Saturday, saying the world’s leading industrialized countries had agreed on common steps to stabilize the markets and shore up the banking system.

“All of us recognize that this is a serious global crisis, and therefore requires a serious global response, for the good of our people,” Mr. Bush said after an early-morning meeting at the White House with finance ministers from the Group of 7 countries.

Mr. Bush said the countries had agreed to general principles in responding to the crisis, including working to prevent the collapse of important financial institutions, and protecting the deposits of savers.

But he offered no details on fresh measures, suggesting that there are still differences between countries about which steps to take, and when, to shore up their respective financial systems. Mr. Bush warned that countries should not undermine one another in their policies.
