Promoting Resilient Supply Chains Act of 2023

Removed 'Subject to the availability of appropriations' from Section 4 (Critical supply chain innovation and best practices), meaning the Assistant Secretary must carry out these activities regardless of whether specific appropriations are made for them.

Removed the annual Report to Congress requirement (former section 4(f)) that required the Secretary to submit a summary of every activity carried out under the Act each year, concurrent with the President's budget submission.

Removed the requirement (former section 4(e)(3)) that the Assistant Secretary enter into agreements with heads of relevant Federal agencies within one year to obtain information, data, or assistance for developing the national strategy report.

Replaced all instances of 'countries of concern' with the more precise phrase 'countries that are described in clause (i) or (ii) of section 6(2)(B),' tying the exclusion to specific statutory criteria (significant national security/economic security risk, or RANSOMWARE Act designation) rather than an undefined term.

Added 'domestic enterprises' alongside 'domestic manufacturers' in several provisions, broadening the scope of entities covered by the bill's requirements and activities.

Restructured the bill: moved the definitions section from Section 2 to Section 6 at the end, added a table of contents in Section 1(b), renumbered all sections accordingly, and renamed 'coordination group' to 'unified coordination group' throughout.

Changed 'non-governmental organizations' to 'covered nongovernmental representatives' in several places, and simplified 'Federal agencies' to 'agencies' in numerous instances, likely reflecting a defined term used elsewhere in the bill.
