Mexican President Vicente Fox has announced the discovery of a new deep-water oil field, which is believed to contain 10bn barrels of crude.
The field is in the Gulf of Mexico, and Mexico says it could be bigger than its largest oil field, Cantarell.
The oil industry provides one third of the Mexican state income. More than half the crude extracted is exported, mainly to the United States.
How much do you want to make a bet that this new revelation causes an immediate change in the diplomacy between the U.S. and our southern neighbors?
