WASHINGTON - President Bush and foreign financial officials staged repeated displays of joint resolve yesterday to combat an unfolding financial crisis, hoping to calm investors whose panic has spread despite bold and accelerating government action.

Yet there was no concrete offer of new moves when Bush spoke on a Rose Garden stage just after daybreak yesterday, flanked by representatives from nearly a dozen nations and international organizations. The fresh message of the day was Bush’s plea that nations work together to address the crisis, avoiding the go-it-alone protectionist trade strategies that worsened conditions during the Great Depression.
