Jerry Brown probably could've picked a better time to head across the Pacific for meetings in China, given the roiling political showdown underway on the Korean peninsula. Nevertheless he and a cohort of 90 business and policy leaders are in Beijing on a mission to increase trade ties between China and the Golden State. The California Governor will spend six days traveling across China in an effort to encourage investors there to put their renminbi, the Chinese currency, into California companies. He's pitching everything from Hollywood to Silicon Valley, green technology and even the state's controversial bullet train. We explore whether trade missions like these really make a difference, and ask how the Governor will know if the trip was a success.
