US and Mexican made a plan to deploy thousands of Mexican troops on the Guatemalan border to choke off the flow of illegal immigrants to persuade President Trump to back off imposing tariffs on Mexican imports.

The plan is for Mexico is to send 6,000 national guard troops in a show of force it said would stem the number of migrants crossing into the country, The Washington Post reported Thursday.

The officials are also considering a change to asylum rules that would force people from Central America to seek refuge in the first foreign country they enter after leaving their homeland, the report said.

The proposal would also allow the US to deport Guatemalan asylum seekers to Mexico and Honduran and Salvadoran asylum seekers to Guatemala.

Earlier Thursday, Trump acknowledged that talks between the two countries were progressing but remained prepared to roll out tariffs Monday unless Mexico “steps up to the plate.”

“We’ll see what happens. But something pretty dramatic could happen,” Trump said in Ireland before heading to Normandy, France, for commemorations marking the 75th anniversary of D-Day. “We’ve told Mexico the tariffs go on. And I mean it, too. And I’m very happy with it.”

On Sunday acting Department of Homeland Security Secretary Kevin McAleenan praised the recent deal reached by the United States and Mexico to handle the migration situation along the two countries’ shared border, while downplaying the criticism of President Trump for threatening to impose tariffs on the U.S.’ neighbor.

Speaking on “Fox News Sunday,” McAleenan said that while people can disagree with Trump’s tactics, the fact remains that Mexico approached the White House with “real proposals” on how to handle the immigration crisis. “Mexico came to the table with real proposals,” McAleenan said. “We have an agreement that, if they implement, will be effective.”

The agreement — announced late Friday in a tweet by Trump — ended a showdown that business leaders warned would have disastrous economic consequences for both the U.S. and one of its largest trading partners, driving up consumer prices and driving a wedge between the two allies. And it represented a win for members of Trump’s own party who had flooded the White House with pleading calls as well as aides who had been eager to convince the president to back down.

“I think, just in general, Republicans understand that tariffs are a tax on American consumers,” Sen. Ron Johnson, R-Wis., said during a separate interview on “Fox News Sunday.” “And we don’t want to see them in place long-term, nor do I believe President Trump does either. He’s using tariffs as leverage in trade negotiations and I think he used them as leverage in this situation brilliantly, quite honestly.”

A “U.S.-Mexico Joint Declaration” released by the State Department said the U.S. “will immediately expand the implementation” of a program that returns asylum-seekers who cross the southern border to Mexico while their claims are adjudicated. Mexico will “offer jobs, health care and education” to those people, the agreement stated.

The United States will also immediately expand the implementation of the existing Migrant Protection Protocols across its entire Southern Border. This means that those crossing the U.S. Southern Border to seek asylum will be rapidly returned to Mexico where they may await the adjudication of their asylum claims.

Mexico has also agreed, it said, to take “unprecedented steps to increase enforcement to curb irregular migration,” including the deployment of the Mexican National Guard throughout the country, especially on its southern border with Guatemala. And Mexico is taking “decisive action to dismantle human smuggling and trafficking organizations as well as their illicit financial and transportation networks,” the State Department said.

Mexican President Andrés Manuel López Obrador tweeted, “Thanks to the support of all Mexicans, the imposition of tariffs on Mexican products exported to the USA has been avoided.” He called for a gathering to celebrate in Tijuana Saturday.

President Trump would have added 5% tariffs on Mexican imports starting Monday if Mexico refused to help with the illegal immigration crisis. The tariffs would have increased by increments of 5% until they hit 25% in October.
