Karen Hathaway, chairwoman of the Los Angeles Area Chamber of Commerce, addresses the opening ceremony of the city's World Trade Week on May 4. The annual event began in 1927 and in the 85 years since has grown to become "the most extensive and unique celebration of international trade in the country," Mayor Antonio Villaraigosa said. Los Angeles is recognized as the US gateway to Asia and a key point in trade with Latin America. [Wang Jun / chinadaily.com.cn]
