Thrilled to have been part of the group of authors who published this piece in @ScienceMagazine How trade policy can support the climate agenda

Delighted to announce the Call for Papers for the 2025 @JIEL_OUP Junior Faculty Forum has now launched! ✍️ All junior scholars in international economic law (and related disciplines) are invited to submit their abstracts for consideration. Details here:

Lean into the history, & inevitably, we can learn about where to go. History highlights the limitations of existing rules in the current context; nevertheless, there remains a thread that connects us to today, helping us better implement procedures & imagine new rules (new paper)

From an amicus brief in one of the IEEPA cases: "[IEEPA] is silent on tariffs, and for good reason. It was never meant, and has never been understood, to authorize the President to impose them. Still less does it permit the Executive to restructure the nation’s trade regime."

Today is obviously a big day for trade disputes, but while we are waiting for news, https://t.co/gfrl1jNrMJ subscribers can check out what happened with trade disputes last month.

One common trade policy misconception is that we had anything close to free trade with China. Yes, China joined the WTO, but loads of tariffs, non-tariff barriers, and subsidies remained in place.

To make sure my IELP blog following never gets too big, I try to do occasional posts on obscure topics such as "optimal tariffs" to scare off the general public: "The Optimal Tariff Argument at the Scott Bessent Hearing" https://t.co/4FYUHWqHbY

Some business groups were concerned about USTR renegotiating investment protection provisions. USTR just released an FTC Decision under the US-Colombia TPA, and if this is all USTR was doing, it doesn't look like a big change to me. https://t.co/iRaq3wYX8I

In the waning days of the Biden administration, I took one of my last opportunities to comment on U.S. Trade Rep. Katherine Tai's trade policy thoughts (also, I tried to lure her into posting on the IELP blog -- we'll see if she takes me up on it!).

Smart take here from @snlester on Sullivan's legacy. Share his critique of Sullivan as to how he promotes ideas as norms: "foreign policy middle class" or "dangerous dependencies" without defining them, setting their scope, or clarifying what concepts they relate to (or replace).

As I’m about to go my first class of jurisprudence for this semester a student brought me this! It will be a fun year!

Bremmer-Sullivan exit interview is worthwhile. I dwelled on tone deafness of US allies. Practice diverts from theory if you examine the EU ramp-up ACI to counter US coercion; costs to other open markets of US industrial policies; the increased closure of US markets to ROW firms.

For everyone who has been waiting so patiently for it, the USMCA panel report in the Mexico - GE Corn case is now out: https://t.co/0clcjbNF00 The Panel found a number of violations, and also found that these violations were not justified under the exceptions.
