The ports of Los Angeles and Long Beach saw a decline in container traffic during 2007 for the first time in at least 20 years.

The complex, which is still the nation’s busiest seaport for cargo containers, also saw a hike in exports due to the dollar’s declining value, which helped U.S. companies break into new markets.

Overall, the ports moved 15.7 million containers in 2007, which was down 100,000 from 2006.

Some economists see the slowdown at the ports as evidence of an economic slowdown.

The report said that finished goods, apparel, toys and electronics make up a majority of imported goods. Exported goods are generally lower-value goods like cotton, animal feed and scrap metal.
