U.S. President Barack Obama on Saturday continued his administration's careful efforts to take credit for the slowly improving economy, using his radio address to tout the economic turnaround since world leaders met in London in April. At the time of the G-20 summit, the world's economic situation was dire, Obama said in the radio address. The meeting in London marked "a crisis that required unprecedented international cooperation to jumpstart the world's economies and help break the downward spiral that enveloped all our nations," he said. Next week, Obama and the same world leaders will gather in Pittsburgh for what Obama called "a five-month checkup" on the financial actions taken by their countries. "Because of the steps taken by our nation and all nations, we can now say that we have stopped our economic freefall," the president said in the address, which is broadcast on the radio and the internet. But the president was quick to note that he is not satisfied with the extent of the recovery in the United States or globally, saying that "stopping the bleeding isn't nearly enough." "Our work is far from over," he said. "We know we still have a lot to do, in conjunction with nations around the world, to strengthen the rules governing financial markets and ensure that we never again find ourselves in the precarious situation we found ourselves in just one year ago."
