BEIJING - China passed another milestone on a 21st century Long March of which Mao Zedong dreamed - to become the world's dominant economic power.
    The world's most populous nation emerged as a net exporter of vehicles for the first time in 2005, raising the specter of intensified competition for ailing US auto makers and other major car manufacturers around the world.
    China exported 172,800 vehicles in last year, including 31,100 passenger cars and nearly 100,000 trucks, an increase of 27% on the year prior, according to customs figures.
    Imports last year totaled 161,600, the vast majority of them sedans and sport-utility vehicles from Japan, Germany and South Korea.
