From the New York Times:
Soaring energy and raw material costs, a falling dollar and new business rules here are forcing Chinese factories to increase the prices of their exports, according to analysts and Western companies doing business here.
The rise was a modest 2.4 percent over the last year. But even that small amount, combined with higher energy and food costs that also reflect China’s growing demands on global resources, contributed to a rise in inflation in the United States. Inflation in the United States was 4.1 percent in 2007, up from 2.5 percent in 2006.
