The reform of Mexico's energy sector signed into law on 20 December opened the door for private companies interested in investing in the country's oil sector. Though Mexico was one of the first countries to nationalise its oil industry, it has lagged far behind Venezuela, Brazil and Colombia, which attracted over $100 billion of foreign financing, in liberalising this sector. This is why the Mexican oil industry is currently considered to be at an interesting threshold, promoting energy generation and with major projects in the pipeline.
