The relationship between China and Los Angeles has been transformed over the past thirty years through the enormous expansion of global trade and imported products made in China. Products arrive in the Ports of Los Angeles and Long Beach and are then transported by truck and rail to huge warehouses to the east of Los Angeles, where they are reloaded for their final destinations across the country. But along every stop of that journey, there are communities and environments dealing with the consequences of trans-Pacific trade. This has resulted in new community-based movements, which have helped bring about major policy changes to address the impacts on environmental, health, labor, and community. Los Angeles, itself a city of immigrants, including from China, has been at the center of these changes, which are beginning to reach back to China too.
