MEXICO CITY (Reuters) - Mexico would accept a U.S. demand on steel in the United States-Mexico-Canada Agreement if the rule took effect at least five years after the trade pact's ratification, Mexican Foreign Minister Marcelo Ebrard said on Sunday.
Mexican lawmakers earlier this year approved the deal, known as USMCA, which would replace the North American Free Trade Agreement. But Democratic lawmakers have held up U.S. ratification over concerns about how labor and environmental provisions would be enforced.
U.S. Trade Representative Robert Lighthizer also made a last-minute demand to restrict the definition of what would constitute North American steel and aluminum under automotive rules of origin, calling for the metals to be "melted and poured" only in North America.
"Mexico has shared that this would bring lots of problems," Ebrard told reporters, adding that Jesus Seade, Mexico's top negotiator for USMCA, would travel to Washington within hours to present Mexico's terms.
"We will tell (the United States) that we will not accept, in any form, for this obligation to take effect the moment the treaty is ratified," Ebrard said.
Mexico would allow the rule for steel to be enforced after at least five years but not accept the tighter rule for aluminum because the country does not produce the metal's raw materials, Ebrard said.
U.S. negotiators had also pushed Mexico to impose tougher controls on its labor standards, including allowing U.S. inspectors to supervise their implementation in Mexico.
Ebrard reiterated the Mexican government's rejection of that proposal, but said Mexico would allow panels composed of experts and a third party to review labor standards.
The USMCA, signed about a year ago, must be passed by lawmakers in all three countries, including the U.S. Congress.
Canada has said it is waiting on ratification in order to move in tandem with the United States.
