White House Press Secretary Jen Psaki said the administration is identifying choke points in supply chains and discussing an immediate path in the future with businesses and trading partners.

In the longer term, policy makers are looking for a comprehensive strategy to avoid bottlenecks and other problems the semiconductor industry has been facing for years.

President Joe Biden is expected to sign an executive order directing a government-wide supply chain review for critical goods in the coming weeks, with the chip shortage a central concern behind the probe.

The order will compel a 100-day review led by the National Economic Council and National Security Council focused on semiconductor manufacturing and advanced packaging, critical minerals, medical supplies and high-capacity batteries, such as those used in electric vehicles.

Additional supply-chain assessments are expected within a year, focused on critical products -- materials, technology and infrastructure -- and other materials tied to defence, public health, telecommunications, energy and transportation.
