In this July 18, 2012 photo, masked employees work as Shin Cheol-soo, standing at right in the background, chief executive of ENA Industry, tours his company's assembly line in Gyeongsan, south of Seoul, South Korea. Shin no longer sees his future in the United States. The South Korean businessman supplied components to American automakers for a decade. But this year, he uprooted his family from Detroit and moved home to focus on selling to the new economic superpower: China. In just five years, China has surpassed the United States as a trading partner for much of the world, including U.S. allies such as South Korea and Australia, according to an Associated Press analysis of trade data.
