Back in October - Mexican official confirms cartel gunmen forced a dozen tanker trucks to dump gasoline at gunpoint
U.S. Reps. Henry Cuellar, D-Texas, and Dan Crenshaw, R-Texas, also signed the letter, which accuses Mexico of trying to “nationalize its economy and renege on its commitments in the USMCA as a means of empowering its failing state-owned petroleum company.”
Nationalizing it's economy and thwarting our not so covert attempts at undermining it! The horrors!
What about the spirit of the US Mexico Canada Agreement ?!
USMCA more like US Marine Corp Agreement 
Plus, gasoline is far more expensive in Mexico, by about 125% in some instances.
Also Californians Flock to Mexico for Cheap Gas as Prices Rise to $6 in State
Californians are traveling to Mexico for cheaper gas, as fuel prices surge following the Russian invasion of Ukraine, according to The San Diego Union-Tribune and the Los Angeles Times.
Awwwww is Mexico kind of immune to your sanctions shitfuckery becauss it nationalized it's oil and gas? 
im rather fascinated how american companies thought they could ship & sell petroleum at a profit to a country that has done its own production and refining since 1938
like do they also ship timber to canada and try to force them to buy it? lmao (though Canada's timber is private, so it could very well be being tendered at inflated costs an american firm could undercut, capitalism is the most rational organization of resources)
canada steals timber off indigenous lands and undercuts the americans. We've had many disputes with the yanks over it because its impossible to compete with theft.
