Should Congress Codify Trump's Trade Deals?

For the purposes of domestic law, the trade deals negotiated by the Trump administration have been concluded as executive agreements, and there is no indication that the administration wants Congress to approve them via statute. Some members of Congress have raised this possibility though.

Trump's Cambodia Trade Deal, Arms Exports, and the Role of Non-Trade Concessions

In this post, I'm going to talk about some aspects of the recent U.S. trade deal with Cambodia that I haven't heard raised yet, including the following questions: (1) Is the decision to allow U.S. arms exports to Cambodia pursuant to this deal designed to boost U.S. manufacturing?

Is Section 122 of the 1974 Trade Act a Fall-Back Option for Trump to Impose Tariffs?

Without IEEPA authority, as we have all discussed, where there is a will, there is a way. In all likelihood, this way involves the expanded use of other statutory authorities, such as Section 232 of the 1962 Trade Expansion Act and Section 301 of the Trade Act of 1974. In

Roundup of IEEPA Hearing Commentary

I listened to today's Supreme Court hearing on the IEEPA tariff cases, but it was clear to me that I am not well-positioned to offer good insights on how the Court might rule. (The transcript is here if anyone wants to give this kind of tea leaf reading a shot themselves).

Is this the end of MFN as we know it? The EU submission on WTO reform and the meaning of development

With the release of the EU submission on WTO reform, it has become clear that the MFN principle’s central role within the WTO architecture is under challenge. As a keystone, it risks the entire bridge falling. Even if the foundations are retained but deemed outdated or unusable, and a

Is Foreign Antitrust Enforcement "Discriminatory" and "Anti-American"?

The House Judiciary Subcommittee on the Administrative State, Regulatory Reform, and Antitrust held a hearing in December on "Anti-American Antitrust: How Foreign Governments Target U.S. Businesses."
