The prevailing sentiment was that the investigation's results would give Donald Trump the opportunity to crack down on steel imports, and that is an opportunity he would most likely capitalize on.
But Trump's move to protect the USA steel industry outside the WTO framework could nonetheless irritate other the world leaders gathered at the larger G20 meeting in Germany this week.
Last year, European Union steel producers sold 3.2 million tonnes of steel to the US, which is the world's largest steel importer. But talk led to tension and the rest of the world was almost united in their opposition to Trump's agenda for the US -and the world.
The G7, which includes Canada, Japan, the USA and several European countries, have called for a solution to global overcapacity in steel, and the European Union has previously accused China of steel dumping while levying duties of its own.
The U.S., he said, "must fix the many bad trade deals it has made".
The EU is the second largest producer of steel in the world after China. Many Republicans-including many in his administration, according to an Axios report-oppose new tariffs.
They will be tested if Trump decides to go ahead and impose new tariffs on steel.
The U.S. has often criticized China for illegally subsidizing the steel and aluminum industries and contributing to a global glut of the metals.
"There is no doubt that this entire line of trade remedy actions regarding national security matters is going to be an issue", said Jacob Kirkegaard, a senior fellow with the Peterson Institute for International Economics.
While this has little directly to do with apparel, should that be the move he makes, Europe has already thrown out threats of a trade war.
"That hurts us, but it also hurts the Americans", he added. An administration official, however, told Reuters last week that the report would be released after Trump spoke with leaders at the Group of 20 summit in Germany later this week.
The European Union has already promised to retaliate if it is hit by US steel tariffs.
President Trump hinted this week that his administration may move to protect the US steel industry from foreign competition, a maneuver popular with his base but likely to upset China ahead of a meeting of the world's largest economies this week. It is unclear whether his message reached U.S. President Donald Trump.
The leaders agreed in the final statement of the G-20 leaders that they would "fight protectionism and all unfair trade practices and recognize the role of legitimate trade defense instruments in this regard".
"We are going to see probably more private conversations about the Section 232 process under way in the USA", said Joshua Meltzer, a senior fellow at the Brookings Institution in Washington. Enacting Section 232 also may violate World Trade Organization rules.
Just last week, Saudi Arabia, Bahrain, and the United Arab Emirates said their decision to close all land, sea, and airport links to Qatar was done to protect their national security and therefore complied with the WTO's national security exemption.
