Mexico's government says it is prepared to consider the addition of "new elements" to the North American Free Trade Agreement, but it will not agree to a complete overhaul of the pact.

"NAFTA is not renegotiable. Mexico is convinced that the free-trade treaty has been beneficial for the three countries," Foreign Secretary Claudia Ruiz Massieu said during a visit to the Mexican consulate in the US city of Tucson.

US President-elect Donald Trump reiterated on Thursday that he intends to renegotiate the accord linking the economies of Canada, the US and Mexico.

The pact "has created employment and growth and has also allowed us to forge bi-national and tri-national chains of production and value," Ruiz Massieu said.

The 22-year-old agreement can be improved with the incorporation of provisions that correspond to a "new reality," she said.

"We will be working with the new government of the United States on how to strengthen our bilateral trade relationship, starting from the reality of the 21st century," the Mexican foreign secretary said.

Billionaire investor Wilbur Ross, nominated by Trump as commerce secretary, said in an interview with CNN that renegotiating NAFTA will be one of his priorities.
