The problem is Washington's leverage has waned just as China's power over the U.S. has grown.
China is now America's biggest creditor. As of March, it held $768 billion of Treasury securities
- about 10 percent of publicly traded debt.
The U.S. needs China's money to finance its budget deficits, which are soaring as Washington tries to end the recession and bolster the U.S. banking system. The Obama administration estimates the budget deficit will hit $1.84 trillion this year. That's four times last year's deficit.
Even so, as Geithner heads to China to meet Monday and Tuesday with top Chinese officials including President Hu Jintao, he brings an ambitious U.S. goal: persuading Beijing to adopt policies that would transform its nation of savers into spenders.
The Obama administration, just like the previous two, is convinced the key to a prosperous global economy rests heavily with China. It wants to get Beijing to rely more on domestic spending, and less on its exports, to power its own economy
- and the world's.
That switch would uncork enormous buying power and help rebalance world trade. It could hasten an end to the global recession. And it could narrow America's huge trade gap because the Chinese would be buying more American products.
China would benefit, too.
"Beijing really wants Washington to be successful in bringing the U.S. economy out of this recession as fast as it can because it is critical to Beijing's own economic growth," said Kenneth Lieberthal, a China expert at the Brookings Institution.
Yet the Chinese have their own priority issue: the explosion of U.S. borrowing. Like any bank worried about its loans, the Chinese have fretted over America's budget gap. In March, Premier Wen Jiabao said: "We've lent a huge amount of money to the U.S. Of course, we are concerned about the safety of our assets."
Those comments, plus remarks by the head of China's central bank about whether the world needs a new top reserve currency to replace the dollar, jolted financial markets.
The Obama administration insists it isn't worried that the mound of debt it's creating will jeopardize America's sterling AAA bond rating. But Treasury officials said Geithner still intends to reassure the Chinese.
Geithner plans to stress that the administration sees the $1 trillion-plus deficits for this and next year as temporary. The deficits are necessary to fund a stimulus package to help lift America out of recession and invigorate a wobbly U.S. banking system, officials say. Once those needs are met, the administration says it will make deficit reduction a top priority.
"The Obama administration believes strongly in fiscal discipline," said a senior Treasury official. If the Chinese raise the deficit issue, Geithner "will listen to their concerns," said the official, who spoke to reporters under rules that didn't allow him to be identified.
Security tensions in Asia also have flared since North Korea's nuclear weapons tests and missile firings. Because China is viewed as a critical player in any successful resolution of a North Korea standoff, Geithner is expected to address the topic with Chinese leaders.
For all the gravity of the crises he faces, Geithner's trip will allow him some time down memory lane. He is scheduled to give a speech Monday at Peking University, where he studied Mandarin Chinese during two summers when he was in college.
Geithner will also hold an event at a Ford Foundation program in Beijing to support the study of economics in the United States. The program was started by his father when the elder Geithner was based in Asia as an official with the Ford Foundation.
But the fact that the administration's chief economic policymaker is going hat-in-hand to the Chinese to explain the soaring deficits shows how much has changed since his predecessor, Henry Paulson, met with the Chinese as the Bush administration's treasury secretary in 2006.
