True or False: In retaliation for the US unilaterally stopping the DP of NAFTA with Mexico, Mexico established compensatory tariffs on a variety of US exports to Mexico which cost American businesses an estimated $1.8 billion.

The assertion that Mexico established compensatory tariffs on US exports in response to the US stopping the DP of NAFTA is not accurate. While there have indeed been instances of trade tensions and tariff impositions between the US and Mexico, the specific event described in the question does not hold up under scrutiny regarding the timeline and implications of the changes in trade policy.

It's important to understand the context of trade relations between the two countries. Retaliatory tariffs can occur in response to perceived unfair trade practices, but the specific claim involving the $1.8 billion estimate is not substantiated by widely accepted economic analyses or trade reports. Thus, the claim is indeed false.
