died that signs saying "Buy American" were on bins of Asian made products. Yet by 2005, about 60% of Walmart's merchandise was imported, compared to 6% in 1984, although others estimated the percentage was 40% from the beginning. In 2004, Walmart spent $18 billion on Chinese products alone, and if it were an individual economy, the company would rank as China's eighth largest trading partner, ahead of Russia, Australia, and Canada. One group estimates that the growing United States trade deficit with China, heavily influenced by Walmart imports, is estimated to have moved over 1.5 million jobs that might otherwise be in the United States to China between 1989 and 2003.
