MEXICO CITY, Nov. 22 (Xinhua) -- Mexican President Andres Manuel Lopez Obrador on Friday asked U.S. legislators not to entangle internal political issues with the ratification of a renewed North American free trade agreement.

"We ask legislators from the two parties (Republicans and Democrats), with all due respect, to help us and not mix an electoral political issue with the approval of the treaty," said the president at his daily regular press conference.

"As to the treaty, I believe it has a consensus or greater acceptance among the people of the three nations," he added, referring to Canada, the United States and Mexico.

Lopez Obrador said that the Mexico-United States-Canada Treaty (T-MEC) must not be held hostage to political differences, as this does not benefit the economic development of the region.

Legislators from the U.S. Republican Party have expressed fears that the possibility of ratifying the T-MEC would be reduced if the process were to continue into next year, due to the 2020 U.S. presidential election and the possibility of an impeachment trial against President Donald Trump.

However, U.S. House Speaker Nancy Pelosi said Thursday that the U.S. Congress could vote on the treaty this year.

The T-MEC agreement seeks to replace the North American Free Trade Agreement, which took effect in 1994.

To come into effect, the T-MEC needs the approval of the legislatures of all three countries. The Mexican Senate is the only one that has approved it so far.
