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.
