The US and China chip war in dates

THE US has in recent years sought to curb exports of cutting-edge semiconductors to China, with Nvidia and other US chip companies lobbying against its tough restrictions.

As Nvidia says it will resume sales of a less powerful AI semiconductor model to China, here is a rundown of the microchip conflict:

August 2022: Biden's Chips Act

Joe Biden, then US president, signs a bill to boost domestic chipmaking, an industry Washington fears China could come to dominate through mammoth state-backed investments.

The Chips and Science Act includes around $52 billion to promote the production of microchips, the tiny components that power almost all modern machinery.

October 2022: Export controls

Washington suddenly restricts exports of some high-end microchips - crucial to the manufacturing of powerful AI systems - to China on national security grounds.

The rules, which also toughen requirements on the sale of semiconductor equipment, aim to limit Beijing's access to state-of-the-art chips with military applications.
