China is exporting more than just cheap products to the US... they're also exporting their pollution to California, according to a study published in the Proceedings of the National Academy of Sciences Journal.

That pollution is contributing to extra smog in the Los Angeles area. A significant amount of Chinese pollution - 20 percent of it - comes from the export industry. Wind blows the smog across the Pacific Ocean in about six days, creating an increase of 12 to 24 percent in the daily sulfate concentrations along the West Coast. RT's Meghan Lopez takes a look at why China's boasts that they have lowered their pollution levels may mean they just exported that pollution to the US.
