In a bid to boost competition and economic growth, the reforms – which were originally proposed to congress last year – require secondary laws to be approved.
The secondary laws are expected to determine the impact of telecoms reforms on Carlos Slim, the world’s richest man, who holds the majority of Mexico’s fixed-line and cellular market.
Nieto is aiming to have the secondary laws approved by congress at the end of April, but he refrained from pushing the laws through in a bid to resist a backlash from conservative rivals.
