OAKLAND (CBS SF) — While the Port of Oakland continues to bustle with activity and both import and exports have increased, the international effects of the coronavirus have shipping officials casting a wary eye to the future.

Imports jumped 7.3 percent last month over January 2019 totals and exports increased 3.3 percent, port officials said.

The good news, according to port officials, is that the U.S. trade war with China has cooled following a January agreement by China to increase purchases from American farmers, many of whom ship goods though Oakland to Asia.

Also, consumer demand both here an overseas has boosted cargo volume though the port.

The bad news is that since the December outbreak of the coronavirus in Wuhan, China, international travel and shipping has taken a hit, with airline flight cancellations, travel restrictions and quarantines potentially putting a damper on economic activity.

These measures already appear to have slowed Chinese manufacturing to some degree and have led some shipping lines to cancel upcoming cargo trips, according to port officials.

“The uptick in January was encouraging but we’re hearing from shipping lines that cargo volume could moderate over the next few months,” said Port of Oakland Maritime Director John Driscoll.
