Mexican President Claudia Sheinbaum has started to adopt a tougher stance in relations with the Trump administration.

Sheinbaum's attitude is seen as an important turning point in the political and diplomatic relations between the two countries. Experts note that this change could impact regional cooperation and mutual agreements. However, it is important to follow official statements and concrete steps on this matter.
