Criticism

It has already entered into two issues, the first one being that it stood against COFEPRIS, that pressured tobacco and alcoholic companies into paying an amount that would be destined to the Secretaría de Salud (Health Bureau) to prevent and treat diseases provoked by tobacco or alcohol.

ConMéxico also opposed the creation of Sinergia.In 2001, three retail companies, Gigante, Soriana and Commercial Mexicana tried to form an association (Sinergia) trying to have a bigger buy volume (to get a lower price) and in that way compete with Wal-Mart.

But the CFC (Comisión Federal de Competencia, Federal Competition Commission) voted against the Sinergia group, because "it was a monopolic practice". Sinergia argued that it wasn't going to have fixed prices, just wanted to unite to create a bigger sales volume.

What is argued here is that the industries that conform ConMéxico are semi-monopolist, and that's what they were accusing Sinergia of.

Taken from La Jornada newspaper:

"A report by ACNielsen, reveals that, for example, transnational Uniliever holds 40 per cent of the deodorant market, or 75% of consommes and 81 per cent of margarines. Another case: Procter and Gamble has 50 per cent of the detergent sales in supermarkets and 31 per cent in shampoos. Kimberly has 56 per cent of the diaper market and 47.7 per cent of the higienic paper. Nestlé, holds 81 per cent of the soluble coffee market, and 91.8 per cent of powder milk."
