That's great. Thank you very much.
My name is David Collins. I'm a professor of international economic law at City St George's, University of London. I'm from Canada, and I have been in the U.K. about 20 years. My main perspective on world trade and investment law, which are my areas of speciality, tends to be from the U.K., but I've always kept an eye on Canada and on global affairs generally in terms of trade and investment.
I'd like to start by saying that I often find myself being asked about the economic impacts of trade wars, trade tariffs and so on. I feel confident that I can comment on that, but I'm a lawyer, so I'm more interested in the international legal implications and the question as to whether what we're witnessing in terms of the onslaught of protectionism—tariffs in particular—is legal under international law.
The short answer is that it is not. Much of what we have seen, specifically coming out of the U.S. but not only the U.S.—we've seen this from China, the EU, India and other places—probably violates the bedrock of the world trading system that was formulated in the 1940s under GATT, which would later become the World Trade Organization, and that spread into all these regional trade agreements. Most notable, from Canada's perspective, is the USMCA or CUSMA, as well as these mega-regionals like the CPTPP and so on.
We're obviously in a very fraught time in world trade. Tariffs globally have never been this high. They're the highest they've been since the end of the Second World War, and we're seeing a lot of moves toward protectionism, again from the U.S. in the forms of tariffs, but also things like export controls and these really sticky non-tariff barriers, such as non-recognition of quality assessment procedures and so on, which I think the EU is particularly known for.
One of the side problems with the U.S. tariffs is that they have caused a glut of a number of commodities—such as steel, aluminum and others—around the world, and the surplus, which is typically coming from China, has been dumped into other countries. This is causing these countries around the world in tandem to impose trade barriers, most noticeably what the EU has done only in the last 48 hours by announcing all these tariffs.
These are a violation of the principles of the GATT. The main justification cited for these measures.... Again, we tend to associate this with the U.S., especially in Canada. We look at the U.S. as the largest trading partner, and we see what's coming out of Washington. This tends to be justified on the basis of national security, and under domestic U.S. law, it's the section 232 tariffs.
If you translate that into international law, this is article XXI of the GATT. This was drafted a long time ago, in the 1940s, and the language of the GATT is notoriously self-judging. That means that a member state of the World Trade Organization can designate whether it feels that it is having an essential security threat as a consequence of its free trade commitments under the GATT, and there is a similar provision under the GATS, which is the services agreement.
The problem with that provision is that, especially in the last five years or so, it has really been exploited. Countries around the world—particularly the U.S., but also others—have been using this as a justification to impose trade barriers for all kinds of things. You might make an argument plausibly for steel, aluminum and so on, but there are all kinds of commodities now. In theory, the way it is framed leaves it beyond the scrutiny of the international tribunal, specifically the World Trade Organization panels.
We do have a case under the WTO that tells us that these decisions can be scrutinized for essential security, but it's a very light-touch scrutiny, and panels tend to allow countries to follow through with this. Even if they didn't, there's not much in the way of enforcement provisions under the WTO.
In the time I have left—because I have a feeling I'm probably taking longer than I think I am—
