In Washington, U.S. President Donald Trump held up a piece of paper along the lawn at the White House Tuesday, saying it was his new immigration deal with Mexico that contains mystery provisions, even as Mexico says it has no idea what he is talking about.
Ebrard said this week that Mexico's Senate would need to be consulted about any such changes.
But there appears to be enough of an agreement that Mexico would immediately be put in the position of trying to implement it, rather than engage in further negotiations.
"No, I'm going to let Mexico do the announcement at the right time", he said, while insisting that the sheet of paper he pulled from the inside of his suit pocket and waved at reporters was part of the document.
Still, he said Mexico's interests are aligned with those of the USA and that it's "doing real things" and policing its borders.
President Donald Trump may have an agreement with Mexico to commit to more "burden-sharing" on the handling of refugees fleeing violence and poor economic conditions in Central America. That's the difference. They couldn't get it'. "We'll do something about it", he said.
The US government has recently identified $21 billion-worth of European Union good imports - including wine - which it said could be subject to tariffs.
It still needs to be approved by Mexico's legislative body, but now those lawmakers know that if they don't give the green light, then Trump's tariffs are back on the table. "If we have to participate in a regional model like the one I have just described, we would have to present that to Congress".
Mexico has also agreed to have these efforts monitored over the next 45 days to see how effective they have been, with Ebrard noting "a lot of things have to happen" over that period.
In his letter to Mexico's Senate, Ebrard says US officials repeatedly pushed Mexico to agree to the safe third country provision, but that Mexico did not accept.
The crux of the deal is that Government of Mexico will take all necessary steps under domestic law to bring the agreement into force with a view to ensuring that the agreement will enter into force within 45 days.
Mexico's ambassador to the U.S. predicted on Sunday that trade in agricultural goods "could increase dramatically" now that tariffs aren't going ahead and if the USMCA, the trilateral trade pact with the U.S., Mexico and Canada created to replace NAFTA, is ratified - but didn't cite a specific deal with Washington on farm purchases.
