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).

Economic and National Security Provisions in U.S. Trade Agreements

A few weeks ago, I wrote a post cautioning everyone to "Beware the 'Securitization' of Trade Policy." So far, however, it looks like my post has been a big failure, as many people seem to be throwing caution to the wind, and instead of being wary

Bound Rates and the Stakes of the Cambodian Trade Deal

Far from being incoherent, the United States’ recent moves against trading partners suggest a unique restructuring of its economic structure, with executive-dominated foreign investments planned to drive much of its future economic growth. I’ll focus on the Agreement concluded with Cambodia for this post. Cambodia has not signed a

The Future of U.S. Big Tech and Social Media (and a Quick Thought on Manufacturing)

As the saying goes, it's difficult to make predictions, especially about the future, but in a piece I wrote for the Baker Institute, I argue that the social media landscape is going to become smaller and more global, with U.S. big tech control declining. Is this just

Tracking Foreign Investments in the U.S. Pursuant to Trump's Trade Deals

According to President Trump and his administration, one of the most important elements of the trade deals they are negotiating right now is the commitments being made by foreign governments and companies to invest in the U.S. The aggregate figures mentioned in this regard have been as high as

Could Congress Extend the USMCA for Another Term?

People have been assuming that the decision on whether to extend the USMCA for another term is up to President Trump, but based on the language of the USMCA related to the upcoming joint review, could Congress actually have the power to make this decision on its own?

Is There No Going Back on Trade? What Is the Path Forward? A Response to Lighthizer

Former U.S. Trade Rep. Bob Lighthizer has a new essay in Foreign Affairs, and I have some thoughts. I'm going to start with his brief big picture points on the direction of U.S. trade policy, and then go through a couple of the specific concepts he emphasizes.

The Section 301 Excess Capacity Investigation Needs Less Madness, More Method

Shortly after the Supreme Court ruled President Trump’s emergency tariffs under IEEPA  unconstitutional, the administration scrambled to rebuild its tariff wall. While the announcement of Section 122 tariffs immediately following the ruling will provide a temporary patch, the U.S. Trade Representative’s office quickly began to utilize another

War Tariffs

This is a co-authored post by Kathleen Claussen and Tim Meyer. Last week, President Trump announced that the United States would be imposing new tariffs of 50 percent of the value of any product coming from any country that sells weapons or provides military aid to Iran.

USMCA Review and Extension Predictions

When the idea of an expiration clause was suggested during the NAFTA renegotiation, I was against it from the start, and Inu and I wrote a pretty critical piece about it at the time. A review is great, we said, let's definitely have reviews, and there are plenty of ways to do that.
