Mexican government had announced plans to contact winners of Democratic and Republican primaries.
Mexico's government, which has criticized Donald Trump's vow to build a huge border wall, said on Thursday it will contact the Republican candidate's campaign and his Democratic rival after their conventions.
The Republican convention ends on Thursday after having confirmed Trump as its standardbearer earlier this week, while the Democrats will formally name Hillary Clinton as their candidate next week.
"Once the Republican and, in the coming week, the Democratic conventions end, we will seek to establish institutional communication with both campaign teams," Foreign Minister Claudia Ruiz Massieu said.
Ruiz Massieu said Mexico's embassy in Washington and consular network were already reinforcing dialogue with the federal and local governments in the United States.
She declined to comment on the Republican Party's election platform, which supports Trump's plan to build a wall covering the entire southern border with Mexico.
But, she said, Mexico will work "with the US government that will be elected in November to review the actions that we must take jointly to make the border more efficient, orderly and safe."
The Mexican government had announced in March plans to contact the winners of the Democratic and Republican primaries in order to rebut "disinformation" that was said about Mexico during the campaign.
Trump has angered Mexicans by saying he would make their government pay for a massive wall to keep out "rapists" and other criminals from crossing the border.
Pena Nieto told CNN earlier this month that his country would not pay for a wall. In March, the Mexican leader said Trump's "strident rhetoric" recalled the rise of Adolf Hitler.
Ruiz Massieu spoke at a news conference previewing President Enrique Pena Nieto's trip to Washington on Thursday and Friday.
The White House talks will focus on security, migration and trade, she said.
