During his three-day visit, Geithner had a flurry of meetings with China's top economic team, including Vice Premier Wang Qishanand chiefs of commerce, finance, banking and securities, among others.

In an hour-long meeting with Geithner Monday, Wang said, "The major task of our economic dialogue is to address the global economic slowdown.

"We will send a message that China and the United States are cooperating substantively to get over the difficult times, which will help boost confidence, promote global financial stability and economic recovery," Wang said.

Geithner told Wang, "The world is going through an exceptionally challenging period now and I think the world has a huge stake in our two countries working closely together to lay a foundation for recovery."

On Monday in a speech to students at China's Peking University, Geithner said that China's investments in the United States "are very safe. ... We have the deepest, most liquid financial markets in the world."

Geithner also struck a positive note on the global economy, citing the initial signs of improvement.
