NEW YORK (CNNMoney) -- While the United States is dealing with high unemployment and Europe struggles to resolve the financial crisis that plagues its economy, China has also become a fresh source of worry.

The Chinese economy is still growing faster than almost anyone else, at least according to official statistics from Beijing, but the latest reports about a slowdown in manufacturing growth and investigations of accounting irregularities, are causing significant damage to many of the main U.S. listed Chinese ADRs.

Over the past month, Sina (SINA) shed 28% of its market cap, Baidu (BIDU) dropped 25%, Sohu (SOHU) fell 37%.

The anticipated slowdown in China has affected many of the commodities. Over the past month, copper plunged more than 23%, crude oil fell almost 10%, and coal stocks (KOL) dropped 25%.

While, emerging markets, and China in particular ,have turned into a major source of growth for luxury brands, the recent reports about a slowdown have impacted shares of upscale retailers like Coach (COH) and Tiffany (TIF).
