Story highlights Mexico has refused repeatedly to pay for Trump's proposed wall

The Mexican government also defended its position in NAFTA negotiations after Trump's tweet

Washington (CNN) The Mexican government on Sunday again stressed its position that it will not pay for President Donald Trump's proposed border wall.

Trump tweeted Sunday morning: "With Mexico being one of the highest crime Nations in the world, we must have THE WALL. Mexico will pay for it through reimbursement/other."

With Mexico being one of the highest crime Nations in the world, we must have THE WALL. Mexico will pay for it through reimbursement/other. — Donald J. Trump (@realDonaldTrump) August 27, 2017

In response, the country's foreign ministry released a statement saying Mexico would not pay for a wall or other physical barrier at the border "under any circumstances."

"This determination is not part of a Mexican negotiating strategy, but a principle of national sovereignty and dignity," the statement said.
