Tesla Inc. has announced that it will build a new factory in Shanghai to create a new megapack battery, which will increase tensions between Beijing and Washington.

While the port of Shanghai was technically in operation during the three-month shutdown due to Covid-19 restrictions, the operations were slowed significantly.

Sixteen production lines in ten Japanese plants have been paused as supplies from Shanghai are slowed to a snail’s pace.

Lack of workers and Covid-related lockdowns have created an epic pileup at the Chinese port.
