BYD celebrates 300 electric buses produced at US plant

China's electric-car maker BYD on Wednesday celebrated the production of the 300th bus at its Lancaster, California, manufacturing plant, a milestone hailed by some officials as a successful example of US-China business collaboration and a great step toward reducing pollution.

The event also celebrated the Antelope Valley Transit Authority, BYD's neighbor and one of its first customers, which is expected to hit 1 million miles of zero-emission bus operations in early May.

"Three hundred buses is a milestone for BYD," said Patrick Duan, BYD's vice-president of operations.
