The moves were a first step, Biden said, to pushing supply chains in the United States, the world's biggest consumer economy, to operate faster.
Biden brought together powerbrokers from ports, unions and big business to hash out how to speedily address a backlog of products that includes 500,000 containers on cargo ships waiting to be offloaded at the clogged ports of Los Angeles and Long Beach.
The Port of Los Angeles will join the Port of Long Beach in stepping up its round-the-clock operations, the White House said earlier, and Walmart and other retailers will expand use of non-peak hours as well.
"I want to be clear. This is an across-the-board commitment to going to 24/7. This is a big first step," Biden said. "But now we need the rest of the private sector chain to step up as well."
