Trump has threatened to impose the levies starting at 5 percents on June 10 if the Mexican government does not agree to do more to tackle an increase in mostly Central American migrants crossing Mexico to enter the United States.
U.S. border officers apprehended more than 132,000 people crossing from Mexico in May, the highest monthly level since 2006.
The two sides started a third day of talks in Washington on Friday to reach a deal.
“If we are able to make the deal with Mexico, & there is a good chance that we will, they will begin purchasing Farm & Agricultural products at very high levels, starting immediately,” Trump said in tweet. “If we are unable to make the deal, Mexico will begin paying Tariffs at the 5 percents level on Monday!”
Officials have said the talks have centered on migration rather than trade.
Marc Short, chief of staff to Vice President Mike Pence, said earlier on Friday that the United States was moving ahead with a legal notification of the tariffs on Mexican goods. “You should anticipate that happening today,” he said at the White House.
The notification could still be turned off over the weekend by the president, Short said. Trump is returning to Washington from a European trip on Friday.
Mexican Optimism
Trump has warned that the initial tariffs on Mexico will be incrementally increased each month up to 25 percents if a migration deal fails to materialize, however.Mexico is scrambling to avoid such a scenario.
“It’s a good sign that talks have not broken down,” Lopez Obrador told reporters in Mexico City. “There is dialogue and an agreement can be reached. I’m optimistic we can achieve that.”
The Mexican president is due to make a statement on Saturday at a meeting of politicians, businesses, and unions in the border city of Tijuana.
Mexico has prepared a list of possible retaliatory tariffs targeting U.S. products from agricultural and industrial states regarded as Trump’s electoral base, a tactic the Chinese regime has also used with an eye toward the Republican president’s 2020 re-election bid.
Such a move would leave the United States fighting trade wars with two of its three largest trading partners.
The United States imposed up to 25 percents tariffs on $200 billion in Chinese imports last month, prompting Beijing to levy its own tariffs on $60 billion in American goods. Trump said on Thursday he would decide later this month whether to hit Beijing with tariffs on an additional list of $300 billion in Chinese goods.
Trump has taken a hard line on immigration and rebalanced global trade in favor of the United States as part of his “America First” agenda.
On Thursday, Mexico said it had offered to send 6,000 national guard troops to its border with Guatemala to secure the crossing. Officials at the talks have indicated that protocols around sending asylum seekers to Mexico or other third countries while their U.S. claims are processed are also part of the mix.
